How to Make One Pot Broccoli Mac and Cheese Recipe

Step 1: Sauté the Vegetables

Start by melting butter in a large stockpot over medium-high heat. Add the sliced baby bella mushrooms and cook them for about 5 to 7 minutes, stirring occasionally, until their liquid has evaporated and they’re beautifully browned. Then toss in the onions and let them soften for 3 minutes before adding garlic for an additional 2 minutes of fragrant sautéing. This creates a flavorful base that will enrich the entire dish.

Step 2: Cook the Pasta and Broccoli Together

Next, stir in the uncooked pasta along with water, half and half, Dijon mustard, crushed red pepper flakes, and a generous pinch of salt and pepper. Bring the pot to a boil, stirring now and then to separate the pasta strands. As soon as it boils, add your fresh broccoli florets. Maintain a medium boil and cook everything uncovered until the pasta is just al dente and tender, with the broccoli perfectly crisp-tender.

Step 3: Remove Excess Liquid if Needed

Check the pot—if there’s more than about half a cup of liquid left, carefully scoop out the extra with a heatproof cup and save it. This step prevents your mac and cheese from becoming soupy while still keeping that creamy bite.

Step 4: Stir in the Cheese

Lower the heat and add the freshly shredded sharp cheddar and grated Parmesan cheeses into the pot, stirring until they melt seamlessly into the sauce, creating that signature velvety texture. If it feels a bit dry at this point, gradually swirl in some of the reserved pasta water to loosen the sauce without losing creaminess.

Step 5: Season to Perfection

Give your mac and cheese a taste and adjust with extra salt and pepper to bring all those flavors into perfect harmony. Now it’s ready to serve and enjoy!

Make Ahead and Storage

Storing Leftovers

After cooling to room temperature, store any leftovers in an airtight container in the refrigerator for up to 3 days. The broccoli retains its texture well, and the cheese sauce stays luscious with proper reheating.

Freezing

You can freeze this One Pot Broccoli Mac and Cheese Recipe if needed. Portion it into freezer-safe containers and freeze for up to 2 months. Keep in mind that broccoli may become a bit softer after thawing, so it’s best enjoyed reheated gently.

Reheating

Reheat leftovers on the stovetop over low heat, stirring frequently and adding a splash of milk or cream to revive the creamy sauce. Avoid microwave reheating without stirring to prevent uneven warming and dryness.

FAQs

Can I use other types of cheese for this recipe?

Absolutely! While sharp cheddar and Parmesan provide great flavor and creaminess, you can experiment with gouda, mozzarella, or even a bit of cream cheese for different textures and tastes.

Is it necessary to remove excess liquid before adding cheese?

Yes, removing excess liquid ensures the sauce isn’t runny and maintains the perfect creamy consistency. If you skip this step, your mac and cheese might be too watery.

Can I add protein to this One Pot Broccoli Mac and Cheese Recipe?

Definitely! Adding cooked chicken, bacon bits, or even sautéed tofu can turn this dish into a more substantial meal while keeping it deliciously cheesy.

What pasta shapes work best for this recipe?

Pasta that cooks in about 7 to 8 minutes works best here. Think elbow macaroni, small shells, or cavatappi. These shapes hold the sauce well and cook evenly with the broccoli.

Can I make this recipe dairy-free or vegan?

You can make substitutions such as plant-based milk and vegan cheeses to create a dairy-free or vegan version. Just keep in mind the texture and flavor will vary slightly but can still be delicious!
