Ingredients You’ll Need

1 tbsp olive oil: This is used to sauté the vegetables and adds a nice depth of flavor. Feel free to substitute with avocado oil if desired.
16 oz. lean ground beef: Provides protein and a rich flavor base. Ground turkey or chicken could work well too for a leaner option.
1 large yellow onion, diced: Adds sweetness and flavor; a sweet onion or red onion can serve as substitutes.
3 stalks celery, diced: Gives crunch and freshness while balancing the flavors in the casserole.
1 green bell pepper, diced: Contributes sweetness and color; you can use a red or yellow bell pepper for a different twist.
1 14.5-oz. can diced tomatoes, undrained: Provides moisture and acidity, bringing all the ingredients together.
2 cups low-sodium chicken broth: Adds richness; vegetable broth works for a vegetarian version.
2 tsp Cajun seasoning: This is the star of the show that brings the dish to life with its bold flavors. You can make your own blend too!
1 tsp kosher salt: Enhances overall flavor.
2 tbsp fresh parsley, chopped: Brightens up the flavors. If fresh is unavailable, dried parsley can be used, but fresh is always best.
2 tsp minced garlic: For that aromatic base, making everything taste better; fresh garlic is preferred.
1 15-oz. can dark red kidney beans, drained: Brings protein and a creamy texture; other beans, like pinto beans, can be swapped in.
1 cup uncooked white rice: Absorbs flavors and thickens the dish. Brown rice can be used, but cooking time may require adjustment.
16 oz. andouille sausage or smoked sausage, sliced: Delivers that signature smoky flavor. If you want less spice, a mild sausage will do the trick.
¼ cup green onions, sliced: Adds a fresh kick to finish the dish.
{optional} hot sauce for serving: Perfect for those who love an extra kick!

How to Make Red Beans and Rice Casserole

Preheat the Oven: Set your oven to 350°F to get it nice and toasty while you prepare the dish.
Brown the Beef: Heat 1 tbsp olive oil in a large skillet or Dutch oven over medium heat. Once hot, add 16 oz. lean ground beef and cook, stirring occasionally for 4-5 minutes until it’s browned.
Sauté Veggies: Toss in the diced onion, celery, and green bell pepper. Cook for an additional 5-6 minutes, until the onion softens and becomes translucent.
Mix in Flavor: Add 1 can of undrained diced tomatoes, 2 cups low-sodium chicken broth, 2 tsp Cajun seasoning, 1 tsp kosher salt, 2 tbsp chopped parsley, and 2 tsp minced garlic. Stir everything well and let it simmer for 10 minutes. You’ll want to inhale that savory aroma!
Combine with Beans and Rice: Remove the skillet from heat and fold in 1 can of drained kidney beans and 1 cup of uncooked white rice, ensuring everything is well mixed.
Transfer to Casserole Dish: Spray a 9”x13” casserole dish with nonstick cooking spray, then transfer the mixture from the skillet into this dish.
Layer the Sausage: Evenly spread half of the sliced 16 oz. sausage on top of the mixture. Cover the baking dish tightly with foil, then pop it in the oven to bake for 60 minutes.
Final Touches: After 60 minutes, take off the foil, give it a gentle stir, and place the remaining sausage slices on top. Cover with foil again and bake for an additional 30 minutes.
Garnish and Serve: When it’s done cooking, sprinkle with ¼ cup sliced green onions. Serve hot with an optional dash of hot sauce for added flavor.

Storing & Reheating

After enjoying this tasty dish, allow any leftovers to cool at room temperature. Store the casserole in an airtight container in the fridge, where it can last for about 3 to 4 days. If you’d like to freeze it, place it in a freezer-safe container for up to 3 months. When you’re ready to enjoy your leftovers, simply reheat slices in the oven at 350°F for about 30 minutes, or until heated through. Just keep in mind that the texture may be slightly different, so consider squeezing a bit of fresh lemon juice over it before serving to brighten the flavors!

Chef’s Helpful Tips

Always brown your meat thoroughly for maximum flavor. If you rush this step, you might miss out on those delicious, caramelized bits.
If using brown rice, you’ll need to increase the cooking time. Soak it for about 30 minutes before baking to help it cook through evenly.
Love heat? Adjust your Cajun seasoning according to your tolerance. Remember, you can always add more, but it’s hard to take it out!
For an even creamier texture, try adding a cup of shredded cheese in the last 10 minutes of baking.
This dish keeps well, so it’s perfect for meal prep or a comforting meal on busy nights.

Recipe FAQs

Can I make this dish ahead of time?

Absolutely! You can prepare the entire casserole a day in advance. Just cover it tightly with foil and store it in the refrigerator. When you’re ready to bake, no need to thaw; just add an extra 10-15 minutes to the cooking time.

Is this casserole freezer-friendly?

Yes! This red beans and rice casserole freezes beautifully. Just let it cool completely after baking, and then transfer it to a freezer-safe container. It can be frozen for up to 3 months. When reheating, do so slowly for the best texture.

What can I substitute for the sausage?

If you prefer a vegetarian option, you can omit the sausage entirely or use a plant-based sausage for the same smoky flavor without the meat. Tofurky or Smart Sausage are great choices!

Can I use another type of bean?

Sure! While dark red kidney beans are traditional, you can swap them for pinto beans or black beans according to your taste preferences. The cooking process will remain the same.
