Cheese Sauce

4 tbsp unsalted butter
4 tbsp all-purpose flour

1 cup shredded Gruyère, Gouda, or Fontina

Optional: ½ cup breadcrumbs

How to Make Creamy Broccoli Mac and Cheese

Before You Begin

Preheat and prepare your cookware as needed. Cooking times and results may vary depending on your equipment and ingredients. Handle dairy gently and avoid boiling after cheese is added to prevent curdling.

1. Cook the Pasta

Bring a large pot of salted water to a boil.
Cook pasta for 7–10 minutes, or until al dente.
Drain and set aside.

2. Cook the Broccoli

Steam or blanch broccoli until tender-crisp, about 3–4 minutes.
Broccoli should pierce easily with a fork but still remain bright in color.

3. Make the Roux

In a large pot, melt butter over medium heat.
Whisk in flour and cook for 1–2 minutes, stirring constantly, until smooth and lightly foamy.

4. Create the Cheese Sauce

Slowly whisk in milk while stirring.
Simmer for 3–5 minutes, or until the sauce thickens enough to coat the back of a spoon.
Season with Dijon mustard, nutmeg (if using), salt, and pepper.

5. Add the Cheese Safely

Remove the pot from heat.
Stir in cheddar and Gruyère until completely melted and smooth.
Do not boil after adding cheese or dairy, as this may cause separation.

6. Add Broccoli and Pasta

Fold in cooked broccoli and pasta until everything is evenly coated with the cheese sauce.

7. Optional: Bake for a Golden Crust

Transfer the mixture to a baking dish.
Top with Parmesan or breadcrumbs.
Bake at 375°F (190°C) for 20–25 minutes, or until the topping is golden and the edges are lightly bubbling.

8. Serve

Serve hot. Refrigerate leftovers promptly and reheat on low heat until steaming hot (do not boil).

Tips for Ultra-Creamy Mac and Cheese

• Freshly shredded cheese melts better
• Melt cheese off-heat to avoid graininess
• Whole milk creates the best texture
• Don’t overcook the pasta
• Add broccoli toward the end to keep color and texture

Storage + Reheating

Refrigerate: 4 days
Freeze: 2–3 months
Reheat:
• Oven 350°F: 15–20 minutes
• Stovetop: add splash of milk
• Microwave: short bursts + stir

Common Mistakes to Avoid (

• Overcooking the pasta, which makes the final dish mushy
• Not draining frozen broccoli well, causing a watery sauce
• Adding cheese while the sauce is boiling (leads to curdling or graininess)
• Using pre-shredded cheese, which contains anti-caking agents
• Skipping the roux step or not cooking it long enough
• Adding broccoli too early and losing its color and texture
• Baking too long, which dries out the pasta
• Forgetting to season the sauce before adding cheese
• Not stirring the sauce while simmering, causing uneven thickening

FAQ

1. Should I use fresh or frozen broccoli?
Both work well. Fresh broccoli gives a crisper, more vibrant texture, while frozen broccoli is faster and more economical. If using frozen, cook briefly and drain excess water to avoid thinning the sauce.

2. How do I keep my cheese sauce smooth instead of grainy?
Use freshly grated cheese, never pre-shredded. Add the cheese after removing the saucepan from heat so it melts gently without separating.

3. Can this recipe be made gluten-free?
Yes. Use gluten-free pasta and replace the flour with a gluten-free 1:1 baking blend. The method remains the same.

4. What proteins taste best in this dish?
Rotisserie chicken, turkey, Italian sausage, ground beef, bacon, or even crispy tofu fit perfectly. Add proteins after the sauce is finished.

5. Can I make this without baking it?
Absolutely. The stovetop version is just as creamy. Baking adds a golden top, but it isn’t required.

6. Can I make this ahead?
Yes. Prepare the dish, assemble it in a baking dish, cover tightly, and refrigerate up to 24 hours. Add 5–10 extra minutes of baking time if cold.

7. What cheese blend gives the best flavor?
Sharp cheddar offers flavor, while Gruyère, Gouda, or Fontina add meltability. Parmesan enhances the savory notes. Stick with at least one sharp cheese + one melty cheese.

8. Why is my sauce too thick or too thin?
Too thick: whisk in additional warm milk.
Too thin: simmer longer or add a tiny pinch of flour.

9. Can this be made spicier?
Yes—add paprika, cayenne, jalapeños, or pepper jack cheese.

10. What pasta shape holds the sauce best?
Elbows, cavatappi, shells, and penne all cling to the cheese sauce beautifully.
