One-Pot Butternut Mac Cheese

A creamy comforting mac & cheese featuring tender butternut squash blended into the sauce (perfect for sneaking in extra veggies without sacrificing flavor)

I first made this as a weeknight twist on classic mac & cheese to add a little color to chilly evenings (the butternut squash makes this pasta silky and satisfying while my family never misses the extra veggies)

Ingredients

• Pasta: 340 g (12 oz) elbow macaroni or small pasta shells
• Vegetables: 400 g (about 3 cups) butternut squash, peeled and cubed; 1 small onion, diced; 2 cloves garlic, minced
• Dairy: 600 ml (2 ½ cups) whole milk; 120 g (1 cup) shredded sharp cheddar cheese; 60 g (½ cup) shredded mozzarella cheese; 30 g (2 tbsp) unsalted butter; 2 tbsp cream cheese (optional, for extra creaminess)
• Seasonings: 1 tsp Dijon mustard; ½ tsp paprika; ½ tsp salt, or to taste; ¼ tsp ground black pepper; Pinch of nutmeg

Instructions

Sauté Aromatics:

In a large pot, melt the butter over medium heat. Add the diced onion and garlic (cook for 2–3 minutes until softened)

Add Squash:

Add the cubed butternut squash and stir for 2 minutes

Simmer:

Pour in the milk and bring to a gentle simmer. Cover and cook for 10–12 minutes, until the squash is fork-tender

Blend:

Use an immersion blender (or transfer to a blender carefully) to blend the mixture until smooth

Cook Pasta:

Return the pot to medium heat. Add the uncooked macaroni, Dijon mustard, paprika, nutmeg, salt and pepper (stir well)

Simmer Pasta:

Simmer uncovered, stirring frequently, for 10–12 minutes, or until the pasta is al dente and the sauce is creamy. Add more milk if needed to maintain a saucy consistency

Add Cheese:

Remove from heat. Stir in the cheddar, mozzarella, and cream cheese (if using) until melted and smooth

Finish & Serve:

Taste and adjust seasoning as needed. Serve warm, garnished with extra cheese or fresh herbs if desired

Recipe FAQs

→ How do I ensure the butternut squash blends smoothly?

Cook the squash until fork-tender, then use an immersion blender or countertop blender to puree it until fully smooth before adding pasta.

→ Can I use other pasta shapes instead of macaroni?

Yes, small pasta shells or similar shapes work well to hold the creamy sauce and blend with the squash.

→ How can I make the sauce creamier?

Adding cream cheese or increasing the amount of shredded cheese enhances the creaminess and richness of the sauce.

→ Is it possible to add protein to this dish?

Stir in cooked, diced chicken or white beans just before serving to boost protein content without altering flavor balance.

→ What can I substitute for cheddar cheese?

Gruyère or Fontina cheeses offer excellent alternative flavors, bringing different nuances to the creamy sauce.

→ Can I adjust the seasoning for a spicy kick?

Adding a pinch of cayenne or smoked paprika after blending spices will add a subtle heat without overpowering.
