Baby bella mushrooms: Their earthy, meaty flavor gives this mac and cheese a sophisticated twist.
White onion: Sautéed onions lend sweetness and aroma that mellows as it cooks.
Garlic: Just a touch, but it brings a deep, irresistible aroma to the whole dish.
Uncooked pasta: Choose a short shape that cooks in 7-8 minutes; it absorbs flavor right in the pot with everything else.
Water: It’s the liquid base for cooking the pasta and veggies all together, keeping things simple.
Half and half: This is where the creaminess comes from, making every bite luscious.
Dijon mustard: Don’t skip it! A spoonful perks up the cheese and brightens all the flavors.
Crushed red pepper flakes: For a gentle, warming heat—feel free to adjust to taste.

Sharp cheddar cheese: Go for freshly-shredded for maximum melt and punchy flavor.
Parmesan cheese: Adds a nutty, salty depth that ties the sauce together.

How to Make One Pot Broccoli Mac and Cheese

Step 1: Sauté the Veggies

Begin by melting your butter in a large stockpot over medium-high heat. Toss in the mushrooms and let them sizzle, stirring occasionally, until they’re browned and most of their moisture has cooked off. This should take about 5-7 minutes and will make your kitchen smell incredible. Next, add the thinly sliced onion and keep sautéing for another three minutes. Finally, stir in the garlic and give everything two more minutes—your flavor-packed veggie base is ready!

Step 2: Cook the Pasta

Now, it’s time to bring everything together for One Pot Broccoli Mac and Cheese. Into the pot go the uncooked pasta, water, half and half, Dijon mustard, crushed red pepper flakes, a good pinch of salt, and a spritz of black pepper. Stir it all up and bring the mixture to a robust boil, giving it a few stirs to make sure the pasta doesn’t stick. Once boiling, gently fold in the broccoli florets and drop the heat just enough to maintain a steady, gentle bubble. Keep the pot uncovered and let the magic happen as the pasta cooks right in the sauce, soaking up all those flavors.

Step 3: Remove Excess Liquid (If Needed)

Chances are your pasta will have soaked up most of the liquid, but double-check. If there’s more than about half a cup left, use a heatproof measuring cup to remove and reserve what you don’t need. Save this liquid—you might want it later for adjusting the final sauce’s consistency!

Step 4: Add Cheese and Finish the One Pot Broccoli Mac and Cheese

This is the moment of cheesy glory. Sprinkle in the sharp cheddar and Parmesan, stirring until everything’s dreamily melted and blended. If your mac and cheese looks a little thirsty, stir in some of that reserved liquid until you reach your perfect creamy texture. Give it a taste and adjust with more salt and pepper if needed. That signature stretch of cheese is calling your name!

Step 5: Serve and Enjoy

Scoop your steaming One Pot Broccoli Mac and Cheese into bowls while it’s hot and gloriously creamy. All that’s left is to dig in and bask in the cheesy, broccoli-packed comfort!

How to Serve One Pot Broccoli Mac and Cheese

Garnishes

Finish each serving with a flourish! Freshly cracked black pepper, a sprinkle of extra Parmesan, or a few chili flakes all add a little extra pizzazz. If you want a pop of freshness, snip a few chives or scatter some fresh parsley right on top.

Side Dishes

Since One Pot Broccoli Mac and Cheese is quite hearty, keep sides light and simple. A crisp green salad with tangy vinaigrette balances the richness beautifully, and a slice of rustic bread is perfect for scooping up every last bit of cheesy goodness. Roasted tomatoes are also a hit alongside.

Creative Ways to Present

If you’re feeding a crowd or want to fancy things up, spoon the mac and cheese into individual ramekins and broil for a couple of minutes with extra cheddar on top. Or, pile into a baking dish, cover with garlicky breadcrumbs, and bake until golden and bubbling for a playful take on a classic casserole-style One Pot Broccoli Mac and Cheese.

Make Ahead and Storage

Storing Leftovers

Transfer any extra One Pot Broccoli Mac and Cheese into an airtight container and chill in the refrigerator. It keeps well for up to three days and reheats like a dream for quick lunches or midnight snacks.

Freezing

If you want to freeze portions for future cravings, simply let the mac and cheese cool completely first. Place in freezer-safe containers—leave a little room at the top for expansion—and freeze for up to two months. For best results, thaw overnight in the fridge before reheating.

Reheating

Warm up your leftovers gently on the stove or in the microwave. If the pasta seems dry, stir in a splash of milk, half and half, or water to bring back the silky texture that makes One Pot Broccoli Mac and Cheese so irresistible.

FAQs

Can I use frozen broccoli instead of fresh?

Absolutely! Just add the frozen florets at the same stage as fresh—they may just need an extra minute or two to heat through. Try to use good-quality, bite-sized frozen pieces for the best texture.

What’s the best pasta shape for One Pot Broccoli Mac and Cheese?

Short shapes like elbow macaroni, shells, or rotini work best since they catch all that cheesy sauce. Look for pasta that cooks in about 7-8 minutes for perfect timing alongside the veggies.

Can I make this dish gluten free?

Definitely! Substitute your favorite gluten-free pasta—just keep an eye on the pasta as it cooks, as it can sometimes require a little less time and liquid. Taste test along the way for doneness.

How can I make this mac and cheese a little spicier?

If you crave extra heat, increase the crushed red pepper flakes or add a pinch of cayenne. A spoonful of sriracha swirled in at the end can also fire things up!

Do I have to use both cheddar and Parmesan?

While the mix gives your One Pot Broccoli Mac and Cheese depth and extra savoriness, feel free to play with other cheeses like Gruyère or Monterey Jack. Just make sure at least one cheese is strong and melts easily for that classic creamy pull.
