🍽 Ingredients for One-Pot Broccoli Mac and Cheese
Here's everything you need and why each ingredient matters:
For the Broccoli Mac and Cheese Sauce:
- ½ stick of butter (4 tablespoons) — the starting point of the cheese sauce. Use unsalted so you control the salt level yourself.
- ¼ cup of all-purpose flour — whisked into the butter to form the roux, which thickens the sauce and keeps it velvety smooth.
- 2 cups of whole milk — adds creaminess and balances the richness of the half & half.
- 2 cups of half & half — makes the sauce noticeably richer and silkier without being too heavy. This is what gives it that restaurant-quality creaminess!
- 2 cups of chicken broth — adds a subtle savory depth and helps cook the pasta right in the pot.
- ½ chicken bouillon cube — intensifies the savory umami flavor of the sauce without overpowering it.
- ½ teaspoon of paprika — adds gentle warmth and a slightly richer color to the sauce.
- ½ teaspoon of mustard powder — the secret ingredient! You can't taste it directly, but without it the sauce falls flat. It enhances the sharpness of the cheddar perfectly.
For the Pasta and Broccoli:
- 12 ounces of pasta shells — their curved shape captures cheese sauce inside each piece for a burst of flavor in every bite. Elbows, rotini, or penne work great too!
- 2 cups of broccoli florets — added at the end so they stay tender without getting mushy. Frozen broccoli works too, just thaw and dry it first.
- 4 cups of shredded sharp cheddar — the star of the show! Always shred from a block, pre-shredded bags have anti-caking agents that prevent smooth melting.
🔪 How To Make One-Pot Broccoli Mac and Cheese
Follow these steps carefully and you'll end up with a perfectly creamy, lump-free broccoli mac and cheese every single time!
Step 1: Make the Roux
Place a large saucepan or Dutch oven over medium heat and add the butter. Let it melt completely, then add the flour all at once. Whisk the two together vigorously until they form a smooth, thick paste. Continue cooking for 2 to 3 minutes, whisking constantly, until it turns light golden and smells slightly nutty. This removes the raw flour taste that would otherwise carry through to the finished sauce.
Tip: Don't rush this step! Those 2 to 3 minutes of cooking the roux make a huge difference in the final flavor.
Step 2: Build the Broccoli Mac and Cheese Sauce
With the heat still on medium, slowly pour in the chicken broth while whisking continuously to prevent lumps. Then add the milk and half & half the same way, a little at a time, whisking as you go. Once everything is smooth, add the bouillon, paprika, mustard powder, and a few grinds of black pepper. Stir well and bring to a gentle simmer.
Step 3: Cook the Pasta in the Sauce
Once the sauce is simmering, add the dry pasta shells directly into the pot. Stir well to submerge everything in the liquid, then cook over medium heat for about 8 minutes, stirring frequently. The pasta absorbs the liquid as it cooks, so keep an eye on the consistency and stir often to prevent sticking. Aim for just al dente at this point because the pasta keeps cooking for another couple of minutes after this.
Tip: Don't walk away during this step! Frequent stirring is key to a creamy, lump-free sauce.
Step 4: Add the Cheese and Broccoli
Reduce the heat to low and add the shredded cheddar in batches, stirring after each addition until fully melted before adding more. Adding it gradually helps it incorporate smoothly rather than clumping. Then stir in the broccoli florets and cook for another 2 minutes until the broccoli is tender and bright green and the sauce is thick and glossy.
Step 5: Taste, Adjust & Serve!
Give everything a final taste and adjust the seasoning with salt and pepper as needed. Serve immediately while it's still hot and at its creamiest! If it thickens too much while sitting, just stir in a splash of warm milk to loosen it right back up.
💭 Pro Tips for the Creamiest Broccoli Mac and Cheese
Want to nail this every single time? Here are the tips that make the biggest difference:
- Always grate your own cheese from a block — pre-shredded bags contain anti-caking agents that prevent smooth melting and can make the sauce grainy.
- Don't overcook the pasta — aim for al dente at Step 3 since it keeps cooking with the cheese and broccoli. Overcooked pasta turns mushy fast!
- Add cheese off the heat or on low — high heat causes cheese proteins to seize up and turn grainy. Low and slow is the way to go!
- Don't skip the mustard powder — you can't taste it directly but it makes the cheddar flavor sharper and more vibrant. It's the secret weapon!
- Add broccoli last — putting it in too early makes it mushy and gray. Two minutes at the end keeps it tender, bright green, and perfect.
🧊 How to Store, Freeze & ♨️ Reheat Broccoli Mac and Cheese
In the Fridge
Store leftovers in a sealed airtight container in the refrigerator for up to 4 days. This broccoli mac and cheese reheats really well, so it's a great option for meal prep too!
In the Freezer
Mac and cheese can be frozen, but keep in mind that the sauce can separate slightly upon thawing due to the dairy content. For best results, freeze before adding the broccoli, then stir in fresh broccoli when reheating. Store in a freezer-safe container for up to 2 months.
Reheating Tips
The best way to reheat this dish is in the microwave with a splash of milk stirred in to loosen the sauce back up. Heat in 60-second intervals, stirring between each, until hot and creamy again. You can also reheat on the stovetop over low heat with a little milk, stirring frequently.
🥗 What to Serve With Broccoli Mac and Cheese
This dish is hearty enough to enjoy on its own as a complete meal! That said, a simple side can round things out nicely, especially if you're serving it for dinner:
- A simple green salad, the freshness and acidity balance the richness of the cheese sauce perfectly.
- Garlic bread or crusty baguette, for scooping up every last drop of that amazing cheese sauce.
- Grilled or baked chicken breast, a lean protein that turns this into a complete, filling dinner.
- Tomato soup, a classic comfort food pairing that works surprisingly well with mac and cheese.
