Detailed Step-by-Step Instructions for Beginners
Preparation Phase
- Set up your cutting station
- Place your cutting board on a flat, stable surface
- Position your cutting board on a damp paper towel to prevent slipping
- Have a small bowl ready for vegetable scraps
- Make sure your knife is sharp (dull knives are more dangerous)
- Prepare the onion
- Cut one medium yellow onion in half from top to bottom
- Peel off the papery skin and remove the root end
- Place the flat side down on the cutting board for stability
- Cut into thin slices, then rotate and cut across to create 1/4-inch dice
- Tip: If your eyes water, refrigerate the onion for 30 minutes before cutting
- Prepare the garlic
- Separate 3 cloves from the garlic bulb
- Place the flat side of your knife on each clove and press firmly with your palm to crush it
- Peel away the papery skin
- Finely chop the garlic by rocking your knife back and forth across the cloves
- Warning: Keep fingers tucked away from the blade while chopping
- Prepare the carrots
- Wash 2 medium carrots under cold water
- Using a vegetable peeler, remove the outer skin completely
- Cut off both ends of the carrots
- Cut each carrot in half lengthwise
- Place the flat sides down and slice into thin strips
- Turn and cut across the strips to create 1/4-inch dice
- Tip: For even cooking, try to make all carrot pieces roughly the same size
- Prepare the red bell pepper
- Wash 1 medium red bell pepper under cold water
- Cut around the stem and pull it out along with the seeds
- Cut the pepper in half and remove any remaining white parts and seeds
- Place the pepper skin-side down and cut into 1/4-inch strips
- Turn and cut across the strips to create 1/4-inch dice
- Tip: Red bell peppers add natural sweetness and bright color
- Prepare the zucchini
- Wash 1 medium zucchini under cold water
- Cut off both ends of the zucchini
- Cut the zucchini in half lengthwise
- Cut each half lengthwise again to create quarters
- Slice across the quarters to create 1/4-inch dice
- Note: No need to peel the zucchini as the skin contains nutrients and will blend smoothly
- Measure remaining ingredients
- Open the can of crushed tomatoes (28 oz)
- Measure 2 tablespoons of tomato paste
- Measure 1/4 cup of heavy cream
- Grate 1/3 cup of Parmesan cheese
- Measure 1 teaspoon each of dried oregano and dried basil
- Measure 1 teaspoon of salt and 1/2 teaspoon of black pepper

Cooking Phase

- Add 2 tablespoons of olive oil to the pot
- Wait about 30-60 seconds for the oil to heat up
- Test if oil is ready: Add a small piece of onion – it should sizzle gently
- Warning: If oil is smoking, it’s too hot; remove from heat briefly and reduce temperature
- Sauté the onions (3-4 minutes)
- Add all the diced onion to the hot oil
- Using your wooden spoon, stir to coat all pieces with oil
- Stir occasionally, every 30-45 seconds

- Add all the diced red bell pepper and zucchini to the pot
- Stir to combine all vegetables thoroughly
- Continue to cook for 4-5 minutes, stirring occasionally
- Optional step: Cover the pot with a lid for 2-3 minutes to help steam and soften the vegetables

Troubleshooting
Common Issues and Solutions

|---|---|---|
| Sauce is too thin | Not enough reduction | Simmer uncovered for additional 5-10 minutes |
| Too much liquid from vegetables | Add 1-2 tablespoons more tomato paste | |
| Sauce is too thick | Too much reduction | Add 1/4 cup vegetable broth or water and stir |
| Too much tomato paste | Add 2-3 tablespoons water and 1 tablespoon cream | |
| Sauce is too acidic | Tomato acidity | Add 1/4 teaspoon more sugar |
| Need more fat to balance | Add 1 tablespoon more cream or 1 tablespoon butter | |
