How to Make Butternut Squash Pasta Sauce
Step 1: Preheat and Prepare
Start by preheating your oven to 450°F (232°C). This high heat helps caramelize the vegetables, bringing out their natural sweetness. Line a baking sheet with parchment paper for easy cleanup.
Step 2: Roast the Veggies
Spread the frozen diced butternut squash, fresh chopped tomatoes, and sliced yellow onion on the baking sheet. Drizzle them with olive oil and season with salt, black pepper, and dried thyme. Toss everything together so each piece gets coated evenly; this step ensures that every bite bursts with flavor!
Step 3: Bake Away
Now it’s time to bake! Pop those seasoned veggies in the oven for about 20 minutes. Roasting will soften them up and enhance their sweetness.
Step 4: Cook Your Pasta
While your veggies are roasting, boil water in a large pot and cook your pasta according to package instructions. Remember to reserve 1/3 cup of pasta water before draining—this starchy liquid will help bring your sauce together later!
Step 5: Blend It Up
Once your veggies are beautifully roasted and tender, take them out of the oven. Add them directly into your blender along with that reserved pasta water. Blend until smooth—this creamy texture is what makes this Butternut Squash Pasta Sauce so delightful!
Step 6: Toss and Serve
Pour the luscious sauce over your cooked pasta and toss gently until everything is well coated. Serve immediately while it’s warm! If you’d like, top with parmesan cheese or plant-based parm for added flavor.
And there you have it—a delicious meal that warms both body and soul! Enjoy every bite of your homemade Butternut Squash Pasta Sauce!
Pro Tips for Making Butternut Squash Pasta Sauce
Creating the perfect butternut squash pasta sauce is all about technique and little details that make a big difference! Here are some pro tips to ensure your dish turns out creamy and delicious every time.
- Choose fresh ingredients: Using fresh tomatoes and onions enhances the flavor profile of your sauce, making it more vibrant and delicious.
- Adjust seasoning to taste: Everyone’s palate is different, so feel free to tweak the salt, pepper, or thyme according to your preference. A little taste-testing can go a long way!
- Don’t skip the roasting: Roasting the vegetables caramelizes their natural sugars, resulting in a deeper, richer flavor that elevates your pasta sauce from good to incredible.
- Blend until smooth: For a truly creamy texture, blend the sauce until it’s completely smooth. This will ensure that every bite of pasta is coated perfectly!
