Why I keep coming back to this recipe
It’s the kind of dish that feels like a hug—familiar, warm, with a seasonal twist. The pumpkin adds a subtle richness that keeps it from feeling heavy, even after seconds. Plus, it’s forgiving enough to experiment with—extra spice, different cheeses—making each batch a little personal. It’s comfort food that feels like a small victory every time I make it.
Breaking down the key ingredients
- Pumpkin puree: Rich and velvety, it adds sweetness and color. Use canned or roasted homemade pumpkin.
- Cheddar cheese: Sharp and tangy, it melts into a smooth, gooey sauce—swap for Gruyère for a nuttier flavor.
- Pasta: A sturdy shape like shells or cavatappi holds the sauce well. Whole wheat adds a nutty note.
- Milk and cream: Create a luscious base—skim milk works, but full-fat gives better richness.
- Breadcrumbs: Optional topping for crunch—use panko for extra crispiness.
- Spices (nutmeg, pepper): A pinch of nutmeg echoes fall’s warmth and enhances the cheese.
- Onion: Sweated until sweet, it deepens the flavor—can skip if you’re in a rush.

Step-by-step to a cozy pumpkin mac and cheese
Step 1: Preheat your oven to 180°C (350°F).
Step 2: Cook 250g (9 oz) of pasta until just al dente, about 8 minutes. Drain and set aside.
Step 3: In a large pan, melt 2 tbsp butter over medium heat. Add 1 cup chopped onion, sauté until translucent, about 5 minutes.
Step 4: Stir in 1 cup pumpkin puree and cook for 2 minutes, until fragrant and slightly caramelized.
Step 5: In a separate bowl, whisk together 1 cup milk, 1 cup heavy cream, and 1 tsp Dijon mustard.
Step 6: Gradually add the milk mixture to the pumpkin in the pan, stirring constantly to prevent curdling.
Step 7: Add 1 ½ cups shredded cheese (cheddar and Gruyère blend). Stir until melted and smooth.
Step 8: Mix the cooked pasta into the cheese sauce. Season with salt, pepper, and a pinch of nutmeg.
Step 9: Transfer everything to a greased baking dish. Top with a handful of extra cheese and breadcrumbs if desired.
Step 10: Bake for 20-25 minutes until bubbly and golden on top.
Cooking checkpoints and tips to get it just right
- Cheese sauce should be smooth, not grainy—keep stirring over low heat.
- Pasta must be just al dente—overcooking makes it mushy after baking.
- Look for bubbling edges when baking—signs it’s hot and ready.
- Top should be golden and crispy—don’t skimp on the cheese or breadcrumbs.
Common pitfalls and how to fix them
- Cheese sauce curdles or separates.? If cheese sauce breaks, lower the heat and whisk in a splash of milk to bring it back together.
- Pasta becomes too soft.? If pasta is overcooked, it turns mushy—next time, reduce boiling time by a minute.
- The topping remains pale or soggy.? If the top isn’t golden, broil for 2-3 minutes—watch closely to prevent burning.
- The sauce is gloopy and stiff.? If sauce is too thick, stir in a little more warm milk until it loosens.
