In a large saucepan over medium heat, melt 1 tablespoon of butter. Add the chopped onion and sauté until soft and translucent, about 3 minutes. Add the minced garlic and cook for 30 seconds until fragrant. Add the diced carrot and bell pepper, sautéing for 5 minutes until they begin to soften.

What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Cook the pasta 1 minute less than al dente — it will finish cooking in the oven and stay firm.
- 2Warm the milk before adding to the roux to prevent lumps and ensure a silky sauce.
- 3Use freshly grated nutmeg — it adds a warm, aromatic depth that pre-ground cannot match.
- 4For an extra golden crust, switch the oven to broil for the final 2 minutes (watch closely).
- 5Let the bake rest 10 minutes after coming out of the oven so the sauce can set for cleaner slices.
- 6Mix breadcrumbs with a teaspoon of melted butter before sprinkling for a more even, crunchy topping.
Adapt it for your goals.
Gluten-free
Swap the pasta for a gluten-free variety (such as brown rice or corn penne) and use a 1:1 gluten-free all-purpose flour blend in the roux. This makes the dish accessible to those with gluten sensitivity.
high proteinHigh-protein
Add 200g of cooked shredded chicken or crumbled Italian sausage to the pasta mixture before baking. This boosts the protein content and makes it a more substantial main dish.
vegetable swapVegetable-swap
Replace the broccoli and bell pepper with 150g chopped zucchini and 150g sliced mushrooms (sauté with the onion). This changes the flavor profile while keeping the dish equally hearty.
lighterLighter
Use low-fat milk in the sauce and reduce the mozzarella to 1/2 cup. Omit the breadcrumbs or replace with whole-wheat panko. This cuts calories while preserving the creamy texture.
