Ingredients

  • Pasta: 340 g (12 oz) elbow macaroni or small pasta shells
  • Vegetables: 2 cups (about 350 g) butternut squash peeled and diced, 1 small carrot peeled and diced, 1 small onion diced, 2 cloves garlic minced
  • Dairy & Cheese: 2 cups (480 ml) whole milk, 1 cup (240 ml) water, 1 ½ cups (150 g) shredded sharp cheddar cheese, ½ cup (50 g) grated Parmesan cheese, 2 tbsp (28 g) unsalted butter
  • Seasonings: ½ tsp salt (or to taste), ¼ tsp ground black pepper, ¼ tsp ground nutmeg (optional), ½ tsp Dijon mustard (optional)

Instructions

Step 1:
In a large pot melt butter over medium heat. Add onion, carrot, and butternut squash. Sauté for 5–7 minutes until vegetables begin to soften. Add garlic and cook 1 minute more.
Step 2:
Pour in milk and water. Bring to a simmer, cover, and cook for 10–12 minutes until the squash and carrot are very tender.
Step 3:
Use an immersion blender to puree the mixture in the pot until smooth and creamy (or carefully transfer to a blender and return to the pot).
Step 4:
Stir in the uncooked pasta, salt, pepper, nutmeg, and Dijon mustard. Bring to a gentle boil, then reduce heat to maintain a simmer. Cook uncovered, stirring frequently, until pasta is al dente and sauce has thickened (about 10 minutes). Add a splash more water or milk if needed.
Step 5:
Remove from heat. Stir in cheddar and Parmesan cheeses until melted and smooth. Adjust seasoning to taste. Serve hot.

Common Recipe Questions

Can I substitute sweet potato for butternut squash?

Yes, sweet potato works well and adds a slightly different but complementary sweetness to the sauce.

How do I ensure the pasta cooks evenly in one pot?

Stir frequently after adding pasta and maintain a gentle simmer. Adding a splash of water or milk if needed helps prevent sticking.

What blender works best for pureeing the vegetables?

An immersion blender is convenient to puree directly in the pot, but a standard blender can also be used carefully.

Can I add more vegetables for extra nutrition?

Absolutely, spinach or other finely chopped greens added near the end of cooking can boost the veggie content without altering texture much.

What should I do if the sauce is too thick or thin?

Adjust consistency by stirring in small amounts of milk or water until you reach the desired creaminess.

Is this suitable for gluten-free diets?

Yes, simply replace regular pasta with gluten-free varieties to accommodate gluten-free needs.
