Step-by-Step Instructions

Preparing the Croutons

1. Set up your workspace:
   • Take out a cutting board, knife, and baking sheet.
   • Find a medium-sized mixing bowl for tossing bread with oil.
   • Grab your measuring spoons for oil and seasonings.
   • Take parchment paper out if using for easy cleanup.
2. Preheat your oven to 375°F (190°C):
   • Turn on your oven and set the temperature dial or digital control to 375°F.
   • Allow 5-10 minutes for full preheating before adding croutons.
   • Position the oven rack in the middle position to ensure even heating.
   • Line your baking sheet with parchment paper (optional but recommended).
3. Prepare the bread:
   • Place your French bread slices on the cutting board.
   • Using a sharp knife, trim off very hard crusts if desired.
   • Cut each slice into approximately 3/4-inch squares (about the size of a sugar cube).
   • You should end up with about 2 cups of bread cubes.
   • TIP: Slightly stale bread (1-2 days old) makes better croutons than super fresh bread.
4. Season the bread cubes:
   • Measure exactly 1 tablespoon olive oil into the mixing bowl.
   • Add bread cubes to the bowl with the oil.
   • Sprinkle with 1/4 teaspoon salt and a small pinch of pepper.
   • Using clean hands or a spatula, gently toss until every piece has a light coating of oil.
   • Make sure to flip and mix thoroughly for even coating.
5. Arrange for baking:
   • Transfer seasoned bread cubes to your prepared baking sheet.
   • Spread them out into a single layer – this is important!
   • Make sure cubes aren’t touching or overlapping for even browning.
   • If they’re crowded, use a second baking sheet rather than piling them up.
6. Bake the croutons:
   • Place baking sheet in your preheated oven.
   • Set a timer for 4 minutes.
   • When timer beeps, open oven and carefully stir croutons with a spatula.
   • Return to oven for another 4-5 minutes.
   • Watch closely during the final minutes as they can burn quickly!
   • They’re done when golden brown and firm to the touch.
7. Cool the croutons:
   • Remove baking sheet from oven using oven mitts.
   • Place baking sheet on a heat-safe surface.
   • Allow croutons to cool completely on the baking sheet (about 5-10 minutes).
   • They will continue to crisp as they cool.
   • Once cooled, transfer to a bowl if not using immediately.

Making the Caesar Dressing

1. Gather your dressing ingredients:
   • Place all dressing ingredients near your work area.
   • Measure each ingredient before starting the mixing process.
   • Have your whisk and small mixing bowl ready.
   • Make sure your egg yolk is at room temperature for better emulsification.
2. Prepare the garlic:
   • Peel 2 garlic cloves by gently crushing them with the flat side of your knife.
   • Remove and discard the papery skin.
   • Finely mince the garlic using a sharp knife (aim for pieces smaller than grains of rice).
   • Use the side of your knife to mash the minced garlic slightly, creating a paste-like texture.
3. Separate the egg (if using whole egg):
   • Crack egg on the edge of a small bowl.
   • Carefully open the shell, keeping yolk in one half.
   • Allow the white to fall into the bowl.
   • Transfer yolk back and forth between shell halves, letting remaining white drop.
   • Place the yolk in your dressing mixing bowl.
   • Save egg white for another use or discard.
4. Create the base mixture:
   • Add the minced garlic to your small mixing bowl.
   • Measure and add 1 teaspoon anchovy paste (if using).
   • Using your whisk, blend these ingredients together until well combined.
   • The back-and-forth whisking motion will help mix them thoroughly.
5. Add the mustard and lemon:
   • Measure 1 tablespoon Dijon mustard and add to bowl.
   • Whisk until mustard is fully incorporated with garlic mixture.
   • Squeeze fresh lemon to measure 2 tablespoons juice (strain out seeds).
   • Add lemon juice to bowl.
   • Whisk everything together until smooth and well blended.
6. Add the egg yolk:
   • Add room temperature egg yolk to the mixture.
   • Whisk vigorously for about 30 seconds.
   • The mixture should begin to look creamy and slightly lighter in color.
   • Caution for Beginners: Raw egg carries a small risk of foodborne illness. Consider pasteurized eggs or the heat treatment method described in the safety section.
7. Emulsify with olive oil (this is the tricky part!):
   • Measure 2 tablespoons olive oil into a separate small container.
   • Position your whisk in the bowl with one hand, ready to whisk continuously.
   • With your other hand, begin adding oil in a very slow, thin stream.
   • KEY TIP: Add literally just a few drops at first, whisking constantly.
   • Continue whisking vigorously while adding oil in a thin stream.
   • This slow process creates the creamy emulsion – don’t rush it!
   • The entire oil adding process should take 1-2 minutes of constant whisking.
8. Check your emulsion:
   • Your dressing should now be noticeably thicker.
   • It should have a smooth, creamy texture without oil separation.
   • The color will be a pale yellow-white.
   • If oil is separating, whisk more vigorously and pause adding more oil.
9. Add final seasonings:
   • Measure and add 1/2 teaspoon Worcestershire sauce.
   • Add 1/4 teaspoon salt and 1/4 teaspoon freshly ground black pepper.
   • Whisk again to incorporate all seasonings evenly.
   • Take a small taste using a clean spoon.
   • Adjust seasoning if needed (more salt, pepper, or lemon juice).
10. Rest the dressing:
    • Let dressing sit for 5 minutes to allow flavors to meld.
    • Re-whisk briefly before using if it sits longer than 5 minutes.
    • The dressing should coat the back of a spoon when ready.

Assembling the Salad

1. Prepare the spinach:
   • If using pre-washed spinach, open package and check for any wilted leaves.
   • For unwashed spinach, fill a large bowl with cold water.
   • Add spinach and swish gently to remove dirt.
   • Lift spinach out of water (leaving dirt behind) and transfer to colander.
   • Rinse under cold running water.
   • Dry thoroughly using a salad spinner or by laying between clean kitchen towels.
   • IMPORTANT: Spinach must be completely dry or dressing won’t stick properly.
2. Prepare the serving bowl:
   • Choose a large bowl that can fit all ingredients with room for tossing.
   • The bowl should be at least twice the volume of your ingredients.
   • A wide, shallow bowl works best for even dressing distribution.
3. Add spinach to bowl:
   • Transfer your clean, dry spinach to the large serving bowl.
   • If any leaves seem too large, tear them into bite-sized pieces with your hands.
   • Avoid cutting spinach with a knife as this can cause browning.
4. Add the dressing gradually:
   • Start with just 3 tablespoons of your prepared dressing.
   • Drizzle it around the perimeter of the bowl rather than in one spot.
   • Using salad tongs or two large spoons, gently lift and turn spinach.
   • Toss with a light touch to avoid bruising the leaves.
   • Continue tossing for about 30 seconds to distribute dressing evenly.
   • Spinach should be lightly coated, not soggy.
5. Check dressing coverage:
   • Look at spinach leaves to ensure light, even coating.
   • If needed, add 1 more tablespoon dressing at a time.
   • Toss again after each addition.
   • Remember: you can always add more dressing, but you can’t remove it!
6. Add Parmesan cheese:
   • Measure 1/4 cup freshly grated Parmesan cheese.
   • Sprinkle evenly over the dressed spinach.
   • Toss gently again to distribute the cheese throughout.
   • The warmth of the spinach will slightly soften the cheese.
7. Add croutons:
   • Add your cooled, homemade croutons to the bowl.
   • If you made them ahead of time, make sure they’re completely cool and crisp.
   • Toss very gently just a few times to mix them in.
   • Over-tossing at this stage can break up your croutons.
8. Final touches and serving:
   • Transfer salad to individual serving plates or leave in serving bowl.
   • Sprinkle remaining 1/4 cup Parmesan cheese on top.
   • Add a few grinds of fresh black pepper over the top.
   • Serve immediately with remaining dressing on the side.
   • Provide small spoons for adding extra dressing if desired.

Troubleshooting

Problem: Dressing is too thick

• Solution: Add 1 teaspoon water or lemon juice and whisk until desired consistency
• Why it happens: Too much egg yolk or oil added too quickly

Problem: Dressing separated or looks curdled

• Solution: Start over with a new egg yolk in a clean bowl, then slowly whisk in the separated dressing
• Why it happens: Oil added too quickly or ingredients not at room temperature

Problem: Spinach wilting too quickly

• Solution: Make sure spinach is completely dry before tossing and only dress right before serving
• Why it happens: Spinach was wet or dressing sat too long on the leaves

Problem: Croutons burned

• Solution: Next time, lower oven temperature to 350°F and check every 3-4 minutes
• Why it happens: Oven runs hot or bread had high sugar content

Problem: Dressing tastes too fishy

• Solution: For next batch, reduce anchovy paste to 1/2 teaspoon and add more lemon juice
• Why it happens: Personal preference – some people are more sensitive to anchovy flavor

Variations & Substitutions

Classic Protein Add-Ins

  • Add 2 cups diced grilled chicken breast (about 2 medium chicken breasts)
  • Season chicken with salt, pepper, and garlic powder before grilling
  • Let chicken rest 5 minutes before cutting into 3/4-inch cubes
  • Add on top of the finished salad
• Shrimp:
  • Add 1 pound cooked, peeled shrimp (about 20-24 medium shrimp)

Vegan Spinach Caesar

1. Replace Parmesan with nutritional yeast (3 tablespoons)
2. Skip the egg yolk and use this vegan dressing instead:
   • 1/4 cup raw cashews (soaked for 2 hours in hot water, then drained)
   • 2 tablespoons fresh lemon juice
   • 1 tablespoon olive oil
   • 1 tablespoon Dijon mustard
   • 1 garlic clove, peeled
   • 1 tablespoon capers (instead of anchovies)
   • 2 tablespoons water
   • 1/4 teaspoon salt
   • 1/4 teaspoon black pepper
   • Blend all ingredients in a blender until completely smooth (1-2 minutes)
   • Add more water, 1 teaspoon at a time, if needed for pourable consistency

Mediterranean Twist

Add these ingredients for a Mediterranean flair:

• 1/2 cup kalamata olives, pitted and halved
• 1/4 cup sun-dried tomatoes, chopped (oil-packed, drained)
• 1/4 cup red onion, thinly sliced (soak in ice water for 5 minutes to reduce sharpness)
• 1/4 cup feta cheese, crumbled (replace half the Parmesan)
• Add ingredients after dressing the spinach, before adding croutons

Storage & Reheating

Dressing Storage

• Transfer unused dressing to a jar or container with tight-fitting lid
• Store in refrigerator for up to 3 days
• Dressing will thicken when cold – let sit at room temperature for 15 minutes before using
• Whisk well before using as it may separate
• If separation occurs, vigorously whisk until recombined

Meal Prep Tips

• Store components separately:
  • Washed, dried spinach in a container lined with paper towels (closes the lid loosely)
  • Croutons in an airtight container at room temperature
  • Dressing in a small jar in the refrigerator
  • Grated cheese in a separate small container
• Pack in sectioned containers for lunch on-the-go
• Include a small container of extra dressing on the side
• Assemble just before eating for best results

Leftover Salad

• Already dressed salad will not keep well (spinach wilts quickly)
• If you must store dressed salad, it’s best consumed within 12 hours
• Store leftovers in airtight container in refrigerator
• Never freeze prepared salad – texture will be completely ruined

Safety Notes & Tips

Raw Egg Safety

• Use the freshest eggs possible (check expiration date)
• Consider pasteurized eggs for safety – they work exactly the same way
• Alternative: Heat treat your regular egg by:
  1. Place whole egg (in shell) in a small pot of water
  2. Heat water to 140°F using a kitchen thermometer
  3. Maintain temperature (not boiling) for 3 minutes
  4. Remove egg, dry off, and crack as usual
  5. The egg will look normal but be safer to use raw
• Pregnant women, young children, elderly, and those with compromised immune systems should avoid raw eggs completely

Pro Tips

• Dry your spinach completely – use a salad spinner or pat between paper towels until no moisture remains
• Tear, don’t cut spinach to prevent browning at the edges
• Make croutons ahead – they stay fresh in an airtight container for 3-4 days
• Room temperature ingredients make for better dressing emulsification – set egg out 30 minutes before preparation
• Use a microplane for finely grating Parmesan – it distributes better throughout the salad
• Massage tougher greens – if using kale or mature spinach, rub leaves between your fingers with a little oil before adding dressing
• Taste as you go – especially with the dressing, adjusting to your preferences
• Pre-dress individual servings if serving guests who may have different dressing preferences
