Step‑by‑Step Instructions for Pumpkin Pasta Sauce
Step 1: Heat the Oil
Begin by heating 1 tablespoon of extra virgin olive oil in a medium skillet over medium heat. Allow the oil to shimmer for about 1 minute, indicating it’s hot enough to sauté. This foundational step sets the stage for caramelizing the onions, which will enhance the overall flavor of your pumpkin pasta sauce.
Step 2: Caramelize the Onions
Add the diced yellow or sweet onion to the skillet, sautéing for approximately 9-10 minutes. Stir occasionally, allowing the onions to become caramelized and lightly golden brown. Watch for that beautiful golden hue to develop, as this will bring out their natural sweetness and depth in your savory pumpkin pasta sauce.
Step 3: Sauté Garlic and Thyme
Stir in 2 minced garlic cloves and 1 teaspoon of dried thyme into the skillet, cooking for an additional 1-2 minutes. As the garlic sizzles, inhale the fragrant aroma that fills your kitchen. It’s crucial to remain attentive here to avoid burning the garlic, which can turn your pumpkin pasta sauce bitter.
Step 4: Blend the Mixture
Next, transfer the caramelized onion mixture to a blender along with 1 cup of pumpkin puree and 1 cup of unsalted vegetable broth. The combination will yield a creamy base for your sauce. Blend starting at low speed, gradually increasing to high, until the mixture is smoothly combined—this should take about 30-60 seconds.
Step 5: Season the Sauce
Once blended, pour the sauce back into the skillet over medium-low heat. Season with salt and pepper to taste, allowing flavors to meld as you gently stir for 2-3 minutes. The pumpkin pasta sauce should become warm and inviting, perfect for coating your favorite pasta or veggie noodles.
Step 6: Serve and Enjoy
Your savory pumpkin pasta sauce is now ready to be served! Spoon it generously over cooked pasta or veggie noodles and toss gently to coat. For an extra touch, consider adding a sprinkle of nutritional yeast or fresh herbs right before serving, creating a delightful autumnal dish bursting with warmth and flavor.
