Creamy, cheesy, and packed with roasted veggies and savory sausage, this casserole is a weeknight hero that tastes like a hug in a dish.

🥦 When Veggies, Cheese, and Sausage Become Magic

There’s something about casseroles that just feels like home. Maybe it’s the bubbling cheese, or the way every bite has just the right mix of hearty, creamy, and comforting. This Cheesy Broccoli, Sausage & Cauliflower Casserole is one of those dishes that’s easy enough for a busy Tuesday night but satisfying enough to serve to company.

The first time I made it, I had leftover roasted veggies and some sausage links that needed using up. I tossed them together, added a cheesy sauce, and popped it in the oven. The result? Pure comfort. The sausage adds big flavor, the cauliflower keeps it light, and the gooey cheese brings it all together.

🛒 Key Ingredients (And Why You’ll Love Them)

Italian Sausage

Mild or spicy, sausage infuses the casserole with rich, meaty flavor and heartiness.

Broccoli Florets

Adds vibrant color and a bit of crunch. Broccoli also balances the richness of the cheese.

Cauliflower

A low-carb base that soaks up flavor and adds satisfying bulk without feeling heavy.

Sharp Cheddar Cheese

Melts beautifully and delivers that bold, cheesy punch that makes every forkful addictive.

Cream Cheese

Creates a creamy, silky sauce that coats the veggies and sausage perfectly.

Garlic & Onion Powder

Simple pantry spices that add savory depth and warmth to the overall dish.

👩‍🍳 Step-by-Step Instructions

Preheat and Prep
Preheat oven to 375°F (190°C). Lightly grease a 9×13 casserole dish.
Steam or Roast the Veggies
Steam or roast the broccoli and cauliflower until just tender. Roasting brings out a nutty flavor, while steaming keeps them bright and fresh.
Brown the Sausage
Remove sausage from casing and cook in a skillet over medium heat until browned and crumbled. Drain excess fat.
Make the Cheese Sauce
In a saucepan, melt cream cheese with a splash of milk. Stir until smooth, then add shredded cheddar, garlic powder, onion powder, salt, and pepper.
Combine Everything
Toss the veggies, sausage, and cheese sauce together in a large bowl, mixing until everything is well-coated.
Assemble and Bake
Pour the mixture into your prepared dish. Top with more shredded cheddar and bake uncovered for 25–30 minutes, or until golden and bubbly.
Cool Slightly & Serve
Let sit for 5–10 minutes before serving to help it set. Then dig in!
