Cheesy sausage casserole is the kind of dish that makes any chilly night better with its layers of smoky sausage, mellow cheese, and tender rice all tucked together in a bubbling casserole. When my oldest son started college, he begged for this recipe to take back to the dorm because just the smell made him think of home.
The first time I made this casserole, we were hosting friends during the holidays. It disappeared in minutes, and everyone wanted the recipe. Since then, it has turned into my go-to for potlucks and cold Friday evenings.
Ingredients
- Smoked sausage links: sliced for deep savory flavor. Choose a brand with real hardwood smoke for the best taste.
- Cooked white rice: adds bulk and soaks up the cheesy sauce. Day-old rice holds its texture best.
- Cream of mushroom soup: gives silky consistency and umami base. Pick a low-sodium option to control saltiness.
- Milk: helps loosen the soup and melt the cheese. Whole milk gives the richest flavor.
- White onion: brings sweetness and depth. Select onions that are firm and heavy for their size.
- Celery: adds an aromatic crunch. Look for crisp, pale green stalks with no soft spots.
- Broccoli: brings color and subtle bitterness. Use fresh broccoli florets and steam them just tender for the best bite.
- Shredded medium cheddar cheese: melts smoothly and gives robust flavor. Grate your own cheese for the creamiest result.
- Seasoned salt: for a savory hit. Pick one with a blend of herbs and a little paprika.
- Salt and pepper: sharpen flavors. Freshly ground pepper is always worth that extra step.
- Olive oil: for browning sausage and veggies. Look for extra virgin for more depth.
Step-by-Step Instructions
- Brown the Sausage:
- Heat olive oil in a large skillet over medium heat. Add the sliced sausage and cook for about five minutes stirring occasionally until it is caramelized and nicely browned on both cut sides. This step enhances the sausage flavor and gives little crispy edges.
- Cook the Vegetables:
- Add the chopped onion and celery to the pan with the browned sausage. Cook for three to four minutes stirring occasionally until the vegetables are soft and the onion is turning translucent. You want everything to smell fragrant and sweet.
- Mix the Wet Ingredients:
- In a large bowl combine the cooked rice cream of mushroom soup and milk. Stir thoroughly until every grain of rice is coated and the mixture looks creamy throughout.
- Combine and Season:
- Add the sausage and vegetable mixture along with cooked broccoli to the bowl with the rice. Add one and a half cups of shredded cheese seasoned salt and a good pinch of salt and pepper. Fold together gently making sure everything is evenly coated with cheese and soup.
- Assemble and Top:
- Spread the mixture evenly in a greased nine by thirteen inch casserole dish. Sprinkle the remaining half cup of cheddar cheese evenly over the top for a golden crust when baked.
- Bake Until Bubbly:
- Bake in a preheated oven at three hundred fifty degrees Fahrenheit for twenty five to thirty minutes until the casserole is bubbling at the edges and the cheese on top is golden and melted. Do not rush this step as this baking time lets all flavors meld and the cheese forms its signature crust.
- Rest and Serve:
- Let the casserole sit for five minutes before serving. This rest helps the casserole slice neatly and keeps everyone from burning their tongues.

I always sneak an extra handful of broccoli into this dish because it soaks up the cheesy goodness and is such a tasty way to get extra vegetables into my kids. My favorite memory is my youngest daughter demanding seconds after confidently declaring she hated broccoli.
Storage Tips
This casserole stores well in the refrigerator for up to four days. Simply cover tightly with foil or plastic wrap. For longer storage freeze individual slices wrapped in foil and pop them straight into the oven or microwave to reheat. If the casserole seems dry upon reheating add a splash of milk and cover loosely with foil.
Ingredient Substitutions
Swap broccoli for peas or green beans if those are what you have. Turkey sausage or even cooked chicken can be used in place of smoked sausage. For a gluten free version search out a gluten free cream soup or make your own with cornstarch thickener and sautéed mushrooms.
Serving Suggestions
This casserole is a meal on its own but pairing it with a bright simple salad or pickled beets makes everything taste fresher. Warm crusty bread is also perfect for soaking up all the creamy sauce. For extra zing serve with hot sauce or tangy mustard on the side.

Cultural Context
Cheesy sausage casseroles have roots in American potluck and church supper traditions where accessible ingredients and hearty flavors rule. Rice casseroles also pop up in Southern and Midwestern cooking as a thrifty way to stretch meat and cheese for a crowd.
