Ingredients
- 1 large, finely diced onion
- 3 cloves, minced garlic
- 2, peeled and grated carrots
- 2, peeled and grated zucchini
- 1 can (28 oz) crushed tomatoes
- 1/4 cup, fresh, chopped basil
- 2 tbsp olive oil
- 1 tsp salt
- 1/2 tsp black pepper
- 12 oz spaghetti
Instructions
- Step 1: In a food processor, combine 2 grated carrots and 2 grated zucchini; pulse until finely chopped and no large pieces remain. Transfer to a bowl and set aside.
- Step 2: Heat 2 tbsp olive oil in a large saucepan over medium heat. Add 1 finely diced onion and 3 minced garlic cloves, sautéing for 3 minutes until translucent and fragrant.
- Step 3: Add the pureed carrot-zucchini mixture to the saucepan, along with 1 can (28 oz) crushed tomatoes, 1/4 cup fresh basil, 1 tsp salt, and 1/2 tsp black pepper. Simmer for 20 minutes, stirring occasionally until thickened.
- Step 4: Bring a large pot of salted water to a rolling boil. Add 12 oz spaghetti and cook for 8-10 minutes until al dente, then drain and reserve 1/2 cup pasta water.
- Step 5: Stir the drained spaghetti into the saucepan with the spaghetti sauce, adding 2 tbsp reserved pasta water to emulsify. Toss until evenly coated and sauce clings to strands.

Total time is about 45 minutes (20 min prep + 25 min cook). A small batch typically covers several meals in the week — store as the recipe directs.
How do I store leftover Hidden Vegetable Spaghetti Sauce?
Transfer to an airtight jar and refrigerate for up to 5–7 days. Most sauces freeze well for up to 2 months — portion into small containers or freezer bags so you can thaw only what you need. Stir before serving; cream- or yogurt-based sauces may separate on standing.
Can I substitute ingredients in Hidden Vegetable Spaghetti Sauce?
Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.
