Ground Beef and Broccoli Casserole
Let me take you back to the week that made this Ground Beef and Broccoli Casserole a permanent fixture in our household. It was one of those chaotic weeks where my to-do list was growing faster than I could manage, and dinner needed to be something comforting, quick, and—most importantly—kid-proof. I opened the fridge and spotted some ground beef and a head of broccoli that needed love.
I’d tried a few casseroles before, but this particular night, I decided to freestyle a little. Cream cheese? Why not. A bit of Dijon? Let’s get fancy. I’ll be honest—I didn’t expect it to be anything more than edible. But by the time I pulled the bubbling, golden tray out of the oven, the aroma alone was enough to stop my kids mid-squabble. That night, dinner disappeared in minutes. Since then, this cheesy ground beef and broccoli casserole has been requested on repeat.
And here’s the best part: you can switch it up depending on what’s in your pantry or who you’re feeding. Whether you’re going for a classic, a low-carb version, or adding a spicy twist, this dish has your back. Let me show you how to make it perfect—every single time.

Ingredients for Ground Beef and Broccoli Casserole
The Casserole
1 lb ground beef (I usually go with 85/15 for the right balance of flavor and fat)
2 cups broccoli florets (fresh works best, but frozen is totally fine if thawed and drained)
1 small yellow onion, finely chopped
2 cloves garlic, minced
½ tsp salt
½ tsp black pepper
1 tsp Italian seasoning
½ tsp paprika (adds just a bit of warmth)
The Creamy Sauce
1 cup sour cream or full-fat Greek yogurt
½ cup cream cheese, softened
¼ cup milk
1 tbsp Dijon mustard
1 cup shredded cheddar cheese
For the Topping
1 cup shredded cheese (I love mixing cheddar and Monterey Jack)
½ cup crushed Ritz crackers or panko breadcrumbs (optional for a crunchy topping)
Ingredient Notes:
You can swap in ground turkey or chicken if you’re watching red meat. Try cauliflower instead of rice for low-carb. And feel free to play with cheeses—Colby, mozzarella, or even pepper jack.
Equipment You’ll Need
9×13 inch baking dish
Large skillet
Mixing bowl
Wooden spoon or spatula
Cutting board and knife
Cheese grater (yes, freshly grated cheese really does melt better)
How to Make Ground Beef and Broccoli Casserole
Preheat your oven to 375°F (190°C) and grease your baking dish.
Brown the ground beef in a large skillet over medium heat until fully cooked. Drain the excess fat.
Add onion and garlic to the skillet. Sauté until soft, about 3–4 minutes.
Stir in broccoli florets and cook for another 3–5 minutes. Don’t overdo it—just enough to start softening them.
Mix the sauce in a large bowl: sour cream, cream cheese, milk, Dijon, and 1 cup of shredded cheese.
Combine beef and veggies with the sauce, stir everything together.
Transfer to the baking dish, spreading evenly.
Top with cheese and crackers (if using).
Bake uncovered for 20–25 minutes until bubbly and golden on top.
Let it rest for 5–10 minutes before serving—it sets up perfectly as it cools.
Tips for the BEST Casserole
Don’t over-steam the broccoli—it’ll get mushy in the oven.
Drain the beef thoroughly to avoid a greasy texture.
Use block cheese and grate it yourself. It melts smoother and tastes richer.
Let the casserole rest before diving in—it thickens up beautifully.
Delicious Variations & Customizations
Classic Rice Version
Add 1 cup of cooked rice into the mixture before baking for a heartier texture. Great for leftovers or bulkier meals.
Keto-Friendly
Swap in steamed cauliflower rice and use full-fat dairy. Skip the cracker topping or replace with crushed pork rinds.
Add Some Heat
Include a chopped jalapeño or a dash of chili flakes in the sauce for a spicy version.
More Veggies
Bell peppers, zucchini, or mushrooms all work well. Sauté before adding.
Creamier Option
Stir in extra cream cheese or a can of cream of mushroom soup. For a healthier touch, use Greek yogurt.
What to Serve with Ground Beef and Broccoli Casserole
I usually pair it with a crisp green salad or a side of buttered green beans. If you’re going for the comfort food experience, a slice of crusty bread or a warm biscuit really makes it shine. A light fruit salad is a refreshing finish.
