Ingredients
Pasta and vegetables
- 1 pound elbow macaroni
- 3 cups small broccoli florets
- 2 medium carrots, grated
- 1 small onion, diced
Cheese sauce
- 4 tablespoons butter
- 1/4 cup all-purpose flour
- 4 cups milk
- 2 teaspoons kosher salt
- 1/2 teaspoon black pepper
- 1 teaspoon dry mustard
- 3 cups shredded cheddar cheese
- 1/2 cup grated Parmesan cheese
Method
- Step 1. Heat the oven to 375 degrees Fahrenheit and grease a 9x13 baking dish.
- Step 2. Bring a large pot of salted water to a boil, cook the macaroni until just shy of tender, and add the broccoli for the last 2 minutes so it softens without losing all of its shape.
- Step 3. Drain the macaroni and broccoli well.
- Step 4. Melt the butter in a saucepan over medium heat, then cook the onion for 3 to 4 minutes until it softens.
- Step 5. Stir in the grated carrots, cook 1 minute, then sprinkle in the flour and cook another minute so the raw flour taste is gone.
- Step 6. Whisk in the milk slowly, then add the salt, pepper, and dry mustard, and cook until the sauce thickens enough to coat the back of a spoon.
- Step 7. Turn the heat low and stir in the cheddar and Parmesan until the sauce is smooth.
- Step 8. Fold the macaroni and broccoli into the sauce, spread the mixture in the baking dish, and bake for 15 to 18 minutes until bubbling around the edges.
- Step 9. Rest the pan for 10 minutes before serving so the sauce settles into the pasta instead of running loose.

Storage & safety
Refrigerate leftovers within 2 hours and use within 4 days. Reheat covered with a splash of milk so the sauce loosens instead of splitting.
Safe minimum internal temperature: 165°F
Rest time: 10 minutes
Cool leftovers in shallow containers rather than leaving a deep pan on the counter.
Reheat leftovers to 165°F before serving hot again.
Do not taste the sauce before the flour has cooked through.
Troubleshooting
- The sauce turned grainy
- Lower the heat and stir in a small splash of warm milk until it smooths out enough to serve.
- The casserole baked up dry
- Add milk before reheating and cover the pan so the pasta can soften back into the sauce.
Recipe rescue notes
- The vegetables made the pan feel watery
-
Likely cause: The broccoli or onion carried too much water into the sauce.
Fix: Let the baked pan rest fully, then stir it gently before serving so the sauce comes back together.
Next time: Drain the pasta and broccoli well, and give the onion a little time to cook down before you add the flour.
Substitutions
- Broccoli
- Use thawed peas or chopped spinach. — If you use spinach, squeeze it dry first so the sauce does not loosen too much.
Carryover / Next Meal Ideas
Next-day baked mac bowls
Reheat leftovers with extra milk and top with chopped tomatoes or a spoonful of salsa for a second supper that feels fresher.
- Stir the reheated mac well before serving so the vegetables and cheese sauce come back together.
