Ingredients for Zucchini Spaghetti Sauce
This recipe features classic Italian sauce components, with the addition of tender zucchini and colorful bell peppers.
| Ingredient | Amount | Notes |
|---|---|---|
| Tomatoes | 6 cups, chopped | Fresh, peeled or canned |
| Zucchini | 2 cups, diced | Unpeeled for texture |
| Onion | 1 large, chopped | Yellow or white |
| Bell Pepper | 1 cup, chopped | Green, red, or orange |
| Celery | 1/2 cup, diced | Optional, for savory depth |
| Garlic | 2 cloves, minced | Or 1 teaspoon garlic powder |
| Tomato Paste | 1 (6 oz) can | For thickness |
| Olive Oil | 2 tablespoons | For sautéing |
| Italian Seasoning | 2 teaspoons | Or oregano, basil, thyme mix |
| Salt & Pepper | To taste | |
| Sugar | 1 tablespoon | Optional, balances acidity |
Preparation Steps
- Prepare the Vegetables: Rinse and chop all produce as indicated. Peel and seed tomatoes if using fresh for a smoother texture.
- Sauté Aromatics: In a large deep saucepan or Dutch oven, heat olive oil over medium heat. Add chopped onions, celery, and bell pepper. Sauté until vegetables begin to soften, about 5–7 minutes.
- Add Garlic & Zucchini: Stir in minced garlic and zucchini. Cook another 3–5 minutes, allowing the zucchini to release moisture and soften slightly.
- Combine Tomatoes and Tomato Paste: Add chopped tomatoes and tomato paste. Stir until well blended and tomato paste is distributed.
- Season: Sprinkle in Italian seasoning, salt, pepper, and sugar. Mix thoroughly.
- Simmer: Reduce the heat to low. Cover loosely and allow sauce to gently simmer for 1–2 hours, stirring occasionally. The sauce should thicken, deepening in flavor and color as excess moisture cooks off.
- Taste and Adjust: Before serving, taste the sauce and adjust seasoning as needed.
Pro Tips for the Perfect Sauce
- Texture: For a chunkier sauce, dice veggies slightly larger. For a smoother sauce, blend a portion of the cooked mixture using an immersion blender.
- Fresh Herbs: Stir in fresh basil or parsley near the end of cooking for vibrant flavor.
- Thickening: If sauce is too thin, uncover pan and simmer until reduced. Tomato paste also enhances thickness.
- Sweetness: Sugar helps balance the acidity in tomatoes but can be omitted for a more traditional savor.
