I first made this on a rainy Tuesday night when I needed to clear out the fridge I tossed everything together and my family called it the best casserole they have ever had
Ingredients
- Smoked sausage links: Choose a high-quality smoked sausage for rich flavor Slice them evenly so each bite gets a bit of meat
- Cooked white rice: Great use for leftover rice Fluffy and absorbs the sauce beautifully
- Cream of mushroom soup: This is your creamy base Look for low-sodium options if desired
- Milk: Thins out the soup and helps make the sauce extra creamy Use whole milk for best results
- White onion: Adds gentle sweetness Pick a firm onion without blemishes
- Celery: Gives a fresh crunch Select stalks that are crisp and vibrant green
- Cooked broccoli: Use heads that are deep green with tightly closed buds Steam until just tender so they hold up in the bake
- Shredded medium cheddar cheese: Melts perfectly throughout Go for block cheese and shred it yourself for the best melt
- Seasoned salt: Brings savory depth Make sure you use your favorite blend
- Salt and pepper: Essential for seasoning to taste Freshly ground black pepper is ideal
- Olive oil: Helps brown the sausage and sauté vegetables Choose extra virgin for flavor
Step-by-Step Instructions

- Add olive oil to a large skillet and warm over medium heat Place sliced sausage into the pan Let it cook for about five minutes stirring occasionally until it is browned on all sides This step builds a rich meaty flavor for the whole casserole
- Sauté the Vegetables:
- Toss in chopped onion and celery Cook them together with the sausage for another three to four minutes Stir frequently until the onion turns translucent and the celery softens These aromatic veggies create a foundation for the dish
- Mix the Sauce:
- Take a large mixing bowl Pour in cooked rice the can of cream of mushroom soup and milk Stir thoroughly so the rice is well coated and everything blends together
- Combine Everything:
- Add the sausage and vegetable mixture to the bowl Toss in the cooked broccoli most of the cheese seasoned salt plus a bit of salt and pepper Use a big spoon to gently combine everything making sure the broccoli stays in good chunks
- Assemble and Top:
- Scoop the mixture into your greased casserole dish Spread it evenly Sprinkle the reserved shredded cheese over the top for that extra golden crust
- Bake:
- Put your casserole dish on the middle rack Bake for twenty five to thirty minutes You want it bubbling hot and the cheese melted to a gorgeous golden brown
- Rest and Serve:
