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.

Recipe FAQs

How do I achieve a smooth butternut squash sauce?

Sauté the squash and vegetables until tender, then puree using an immersion or standard blender until silky and smooth before adding pasta.

Sharp cheddar and Parmesan provide a rich, tangy flavor and smooth melt that enhance the creamy vegetable base.

How do I prevent the pasta from sticking?

Can I add more vegetables to this dish?

Yes, adding spinach in the last few minutes of cooking is a great way to boost nutrition without altering texture much.
