Prep Time: 10 minutes

Cook Time: 10 minutes

Total Time: 20 minutes

Yield: 4 servings

Ingredients

• 8 oz (225g) pasta of choice (linguine, fettuccine, penne, or fusilli work well)
• 1 tbsp olive oil
• 1 small yellow onion, chopped
• 4 cloves garlic, minced
• 2 cups (approx. 1 lb or 450g) peeled and diced butternut squash (1/2-inch cubes)
• 1 cup vegetable broth
• 1/2 cup unsweetened plant-based milk (oat, soy, or cashew milk recommended)
• 1/4 cup nutritional yeast
• 1 tbsp fresh lemon juice
• 1/2 tsp dried sage (optional, but highly recommended)
• Salt and freshly ground black pepper to taste
• 2 cups fresh spinach (optional)
• Fresh parsley or toasted pumpkin seeds, for garnish (optional)

Step-by-Step Instructions

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add the pasta and cook according to package directions until al dente. Before draining, reserve about 1 cup of the starchy pasta water. Drain the pasta and set aside.
2. Sauté Aromatics: While the pasta cooks, heat the olive oil in a large skillet or pot over medium heat. Add the chopped onion and cook for 3-4 minutes until softened and translucent. Add the minced garlic and dried sage (if using), cooking for another minute until fragrant, being careful not to burn the garlic.
3. Cook the Squash: Add the diced butternut squash to the skillet along with the vegetable broth. Bring to a simmer, then reduce heat, cover, and cook for 8-10 minutes, or until the squash is very tender and easily pierced with a fork.
4. Blend the Sauce: Carefully transfer the cooked squash mixture (squash, broth, onion, garlic) to a high-speed blender. Add the plant-based milk, nutritional yeast, and lemon juice. Blend until completely smooth and creamy. If the sauce is too thick, add a splash of the reserved pasta water until it reaches your desired consistency. Taste and season with salt and pepper as needed.
5. Combine and Serve: Return the smooth sauce to the skillet over low heat. Add the cooked and drained pasta. If using, stir in the fresh spinach until it wilts, which should only take about 1-2 minutes. Toss everything together until the pasta is evenly coated in the creamy sauce. If the sauce seems too thick, add a little more reserved pasta water until it’s perfectly luscious.
6. Garnish and Enjoy: Serve immediately, garnished with fresh parsley or toasted pumpkin seeds, if desired.

Pro Tips for Success

• Pre-Cut Squash for Speed: To truly hit that 20-minute mark, opt for pre-cut butternut squash from the grocery store. It saves valuable prep time and ensures uniform cooking.
• Don’t Overcook the Pasta: Al dente pasta holds up best to the creamy sauce and prevents a mushy texture. It will continue to cook slightly when tossed with the warm sauce.
• Adjust Sauce Consistency: The beauty of this sauce is its adaptability. If it’s too thick, thin it out with reserved pasta water or a splash more plant-based milk. If you prefer it thicker, let it simmer gently for an extra minute or two.
• Enhance Flavor with Sage: While optional, dried sage truly complements the sweetness of butternut squash and the richness of the garlic, adding an aromatic depth that elevates the entire dish.

Variations & Substitutions

• Gluten-Free Option: Simply use your favorite gluten-free pasta. The sauce is naturally gluten-free.
• Add Extra Protein: Stir in a can of drained and rinsed cannellini beans or chickpeas along with the pasta for a protein boost. Cooked lentils would also work beautifully.
• Spice It Up: For a touch of heat, add a pinch of red pepper flakes with the garlic and onion.
• Greens Galore: Instead of or in addition to spinach, try stirring in chopped kale or Swiss chard during the last few minutes of cooking until wilted.
• Herb Swaps: If sage isn’t your preference, try a pinch of dried thyme or a sprig of fresh rosemary cooked with the squash for a different aromatic profile.

Serving Suggestions

This creamy garlic butternut squash pasta is a complete meal on its own, but it pairs wonderfully with a simple, crisp green salad dressed with a light vinaigrette. A side of crusty garlic bread or a warm baguette is also fantastic for soaking up every last drop of that luscious sauce. It’s best enjoyed fresh and warm, making it an ideal weeknight dinner or a satisfying quick lunch.

Storage & Reheating

• Refrigerator: Store any leftovers in an airtight container in the refrigerator for up to 3-4 days.
• Reheating: To reheat, gently warm the pasta in a skillet over medium-low heat, adding a splash of vegetable broth or plant-based milk to loosen the sauce and restore its creamy texture. You can also microwave it, stirring halfway through, but the stovetop method yields better results.
• Freezing: Freezing is not recommended for this dish, as pasta can become mushy and the sauce’s texture may change upon thawing.

Frequently Asked Questions

Can I make the sauce ahead of time?

Yes, you can prepare the butternut squash sauce up to 2-3 days in advance and store it in an airtight container in the refrigerator. When ready to serve, gently reheat the sauce on the stovetop and then toss with freshly cooked pasta.

Can I use frozen butternut squash?

Absolutely! Frozen diced butternut squash works perfectly. You may need to cook it for a few minutes longer than fresh squash to ensure it’s fully tender before blending. No need to thaw beforehand.

How can I make the sauce thicker or thinner?

For a thicker sauce, you can reduce the amount of vegetable broth slightly or simmer the sauce gently for a few extra minutes after blending. To thin it out, simply add more reserved pasta water or plant-based milk, a tablespoon at a time, until it reaches your desired consistency.
