How to Make One-Pot Sausage and Rice Casserole Recipe

The dish is a creamy risotto with visible layers of soft, yellow rice mixed with small pieces of round, browned sausage slices scattered evenly throughout. There are thin, slightly curved strips of red pepper and slender green beans placed on top and mixed within the risotto, adding bright red and green colors contrasting with the yellow creamy base. The texture of the rice is smooth and thick, clumping gently around the sausage and vegetables.

Step 1: Brown the Sausage

Start by heating 2 tablespoons of olive oil in a large pot over medium heat. Slice your sausage into about half-inch pieces, then cook them until browned and heated through—this usually takes just a few minutes with pre-cooked sausage. Removing the sausage at this stage keeps it from overcooking later and lets you build flavor in the same pot.

Step 2: Sauté Onions and Garlic

Next up, melt the butter in the same pot. Toss in the diced onions and cook them gently until they’re soft and translucent—about 5 minutes. Adding minced garlic after keeps it bright and fragrant but prevents burning, so stir it for just one minute.

Step 3: Cook the Rice with Broth

Add the remaining 1 tablespoon of olive oil to the pot along with the chicken broth. Use a silicone spatula to scrape up all those delicious browned bits from the sausage stuck to the bottom—this trick amps up your flavor. Bring the broth to a boil, then stir in the rice and cover tightly. Lower the heat to a simmer and let it cook for 10 minutes.

Step 4: Add Bell Peppers and Finish Cooking

Lay the sliced red and green bell peppers right on top of the rice — don’t stir! This helps the rice cook evenly and get a perfect sticky texture. Replace the lid and continue cooking for 5 to 10 more minutes, watching the rice package’s instructions closely for total time. Then, turn off the heat and let it sit, still covered, for 10 minutes. This resting time lets any rice stuck to the bottom soften and makes stirring easier.

Step 5: Stir in Creamy Goodness and Sausage

Finally, return the pot to low heat. Stir in the cream of chicken soup, sour cream, milk, and shredded cheddar cheese until you get a luscious, creamy mixture. Add back your sausage slices along with red pepper flakes if you want a bit of heat. Warm everything through, then remove from heat and serve.

Pro Tips for Making One-Pot Sausage and Rice Casserole Recipe

  • Rice Choice Matters: I used white long grain rice because it stays fluffy and cooks evenly in this recipe—other types may require liquid adjustments.
  • Scrape That Pot: Don’t skip scraping up the browned bits after adding broth; that’s where a lot of the flavor lives!
  • Don’t Stir Early: Leaving the peppers on top without stirring while it simmers helps with texture and prevents mushy veggies.
  • Taste Before Seasoning: Since the sausage and canned soup add salt, be sure to taste before adding more salt or seasoning.

How to Serve One-Pot Sausage and Rice Casserole Recipe

sausage and rice casserole - Serving Suggestion

Garnishes

I like to sprinkle fresh chopped parsley on top right before serving to add a pop of color and a mild, fresh flavor. A little extra shredded cheddar cheese melted on top never hurts, and for some extra zing, a few dashes of hot sauce work wonders.

Side Dishes

This casserole stands well on its own, but sometimes I serve it alongside a crisp green salad or steamed green beans to add freshness and balance. Garlic bread or crusty rolls also pair beautifully when you want something to soak up the creamy sauce.

Creative Ways to Present

For special occasions, I’ve served this casserole in individual ramekins topped with extra cheese and broiled briefly for a golden crust. It makes the meal feel extra special and is great for portion control or entertaining guests.

Make Ahead and Storage

Storing Leftovers

I store leftovers in airtight containers in the fridge for up to 4 days. The casserole actually tastes better the next day once the flavors meld even more, making it a perfect make-ahead meal for busy nights.

Freezing

This recipe freezes surprisingly well! I portion it into freezer-safe containers and freeze for up to 3 months. Just thaw overnight in the fridge before reheating for best results.

Reheating

Reheat leftovers gently on the stovetop with a splash of milk or broth to bring back creaminess, or microwave in short bursts stirring in between to avoid drying out. This keeps your casserole tasting fresh without losing texture.

FAQs

  1. Can I use uncooked sausage for this casserole recipe?

    Yes! If you prefer raw sausage, brown it thoroughly in the pot before removing it and proceeding with the recipe. This ensures it’s fully cooked and flavors the dish well.

  2. What type of rice works best in this recipe?

    I recommend using white long grain rice because it cooks evenly and results in a fluffy texture. Other rice types can be used but may need adjustments to liquid and cooking time.

  3. Can I make this casserole dairy-free?

    Absolutely! Use dairy-free cream soup alternatives, plant-based sour cream and milk, and skip the cheese or use a dairy-free cheese substitute to keep it creamy and delicious.

  4. Is this recipe freezer-friendly?

    Yes, it freezes very well. Portion it into containers, freeze for up to 3 months, and thaw overnight before reheating.

  5. Can I add other vegetables to this casserole?

    Definitely! Vegetables like mushrooms, zucchini, or spinach mix in nicely and add extra nutrition and flavor.

Ingredients

Scale

Sausage and Rice

  • 3 tablespoons olive oil, separated
  • 11 oz sausage, sliced into ½-inch thick slices
  • 2 tablespoons butter
  • ½ cup yellow onion, diced
  • 2 cloves garlic, minced
  • 2 ½ cups chicken broth
  • 1 ¼ cups white long grain rice, uncooked
  • 1 small red bell pepper, sliced
  • 1 small green bell pepper, sliced

Creamy Mixture

  • 10.75 oz cream of chicken soup
  • ½ cup sour cream
  • ¾ cup milk
  • 1 cup cheddar cheese, shredded
  • 1 pinch red pepper flakes, optional

Instructions

  1. Cook the sausage: Heat 2 tablespoons olive oil in a large pot over medium heat. Slice the sausage into ½-inch thick slices and cook according to package instructions until browned and heated through. Remove the sausage from the pot and set aside.
  2. Sauté onions and garlic: Melt 2 tablespoons butter in the same pot, then add the diced onions and cook until softened, about 5 minutes. Add the minced garlic and cook for 1 more minute until fragrant.
  3. Deglaze and add broth: Add 1 tablespoon olive oil and pour in the chicken broth. Use a silicone spatula to scrape up the browned bits from the bottom of the pot, incorporating those flavorful remnants into the broth.
  4. Add rice and cook: Bring the mixture to a boil, then stir in the uncooked rice. Cover the pot tightly and reduce heat to a simmer. Cook for 10 minutes.

  6. Rest the rice: Turn off the heat and keep the pot covered. Let the rice rest for 10 minutes to allow any stuck rice to release and the flavors to meld.
  7. Make it creamy: Return the pot to low heat. Add cream of chicken soup, sour cream, milk, and shredded cheddar cheese. Stir gently to combine until creamy and well mixed.
  8. Finish with sausage and spice: Add the cooked sausage slices back into the pot along with the optional pinch of red pepper flakes. Stir and cook over low heat until everything is heated through.
  9. Serve: Remove from heat and serve hot for a comforting and easy one-pot meal.
