Ingredients

15 ml (1 tbsp) extra virgin olive oil
150 g (1 medium) yellow or sweet onion, diced

240 g (1 cup) pumpkin puree
1 g (1 tsp) dried thyme
15 g (1 tbsp) minced garlic
180 ml (3/4 cup) unsalted or low-sodium vegetable broth
Salt and black pepper to taste

Steps

Caramelize onions – Heat olive oil in a medium skillet over medium heat. Add diced onion and cook 9–10 minutes, stirring occasionally, until golden brown and sweet.
Add flavor base – Stir in garlic and thyme. Sauté 1–2 minutes, keeping an eye out so the garlic doesn’t burn.

Blend sauce – Transfer onions, garlic, pumpkin puree, and broth to a blender. Blend low, then high, for 30–60 seconds until smooth.
Season – Taste and adjust with salt and pepper.

Serve – Toss with cooked pasta or veggie noodles. This batch coats 16 oz pasta beautifully.

Cooking Tips

Use fresh thyme if you have it for a brighter herbal note.
If you like heat, a pinch of red pepper flakes adds a fun kick.

For a richer flavor, swap olive oil for vegan butter.
If your sauce feels too thick, loosen with a splash of pasta water—it adds silkiness too.
Want extra nutrition? Stir in spinach or kale before serving.

What to Serve

This pumpkin pasta sauce pairs beautifully with fettuccine, penne, or rotini. For a lighter twist, toss it with zucchini noodles or spaghetti squash. Add roasted veggies—like Brussels sprouts or mushrooms—for extra heartiness. It’s also fantastic with garlic bread and a side salad. If you’re feeling indulgent, top it with toasted walnuts or a sprinkle of vegan parmesan for crunch and depth.

How to Store

Let the sauce cool completely before storing. In the fridge, it’ll keep in an airtight container for up to 4 days. For longer storage, freeze in portions—ice cube trays are great for single servings. Reheat gently over medium-low heat, adding a splash of broth or water to loosen if needed.
