During one of those Midwest snowstorms that make you want to hibernate, I stumbled into a cozy kitchen experiment. I had a fridge full of leftovers, a craving for something hearty, and no interest in running to the store.

⁠

That’s when I saw the sauerkraut tucked behind a half-empty jar of pickles, a coil of smoked kielbasa, and a can of tomato soup from last month’s pantry haul. It wasn’t a glamorous start, but what came out of my oven an hour later was one of the most comforting meals I’ve ever had.

What surprised me most was how the tangy sauerkraut mellowed out in the oven, mingling with savory sausage and rice that soaked up every bit of flavor. It reminded me of the simple casseroles my grandmother used to make—rustic, filling, and made with love. Since then, this Easy Sauerkraut Casserole has become a regular in my kitchen, especially when I need something reliable, fuss-free, and deeply satisfying.

I’ve played with the seasoning, swapped in different sausages, and even made it for friends who swore they didn’t like sauerkraut—every single one of them cleaned their plates. Whether you’re cooking for a family dinner, a potluck, or just yourself on a cold night, this casserole delivers warmth and flavor without much effort. Let’s dig into it.

Short Description

This Easy Sauerkraut Casserole is a comforting, one-dish wonder made with smoky sausage, tangy sauerkraut, tender rice, and a rich tomato base—baked until perfectly cozy and satisfying.

Key Ingredients

1 pound kielbasa or smoked sausage, sliced into half circles
1 cup raw white rice
2 cups sauerkraut, drained
½ cup green bell pepper, chopped
1 medium yellow onion, chopped
1 (11 oz) can tomato soup
11 oz hot water (use the empty soup can to measure)
Non-stick cooking spray

Tools Needed

9×13-inch baking dish
Cutting board and knife
Medium mixing bowl or large measuring cup
Aluminum foil
Measuring cups and spoons
Wooden spoon or spatula

Cooking Instructions

Step 1: Prep the Casserole
Preheat your oven to 350°F (175°C). Lightly spray a 9×13-inch baking dish with non-stick cooking spray to prevent sticking and ensure easy cleanup.

Slice the sausage into bite-sized half circles. Chop the onion and bell pepper. Drain the sauerkraut thoroughly—squeeze out extra moisture if needed.

Step 2: Layer the Ingredients
Spread the uncooked white rice evenly across the bottom of the baking dish. Next, layer the drained sauerkraut over the rice. Distribute the sliced sausage evenly over the sauerkraut layer. Sprinkle the chopped green pepper and onion on top.

Step 3: Mix the Sauce
In a mixing bowl or large measuring cup, whisk together the tomato soup and hot water until smooth. Pour this mixture evenly over the casserole, ensuring all the layers are moistened.

Step 4: Bake Covered
Cover the casserole dish tightly with aluminum foil to trap moisture and help cook the rice. Bake in the preheated oven for 45–55 minutes, or until the rice is tender and most of the liquid has been absorbed. Check around the 45-minute mark, especially if your oven runs hot.

Step 5: Rest and Serve
Once done, let the casserole rest for 5 minutes before serving. This gives the rice a moment to finish absorbing any remaining liquid and makes slicing easier.

Why You’ll Love This Recipe

Mistakes to Avoid & Solutions

Mistake 1: Not draining the sauerkraut well
Problem: Excess liquid can lead to soggy rice.
Solution: Press the sauerkraut gently with paper towels or use a sieve to squeeze out extra moisture.

Mistake 2: Using instant rice
Problem: It cooks too quickly and becomes mushy.
Solution: Stick with raw white long-grain rice for the best texture.

Mistake 3: Not covering the casserole
Problem: Uncovered baking causes the top layer to dry out.
Solution: Always cover tightly with foil to trap steam and cook the rice evenly.

Mistake 4: Overbaking
Problem: This can dry out the dish or burn the edges.
Solution: Start checking around 45 minutes and remove once the rice is tender and the liquid is absorbed.

Mistake 5: Adding raw sausage
Problem: Some raw sausages release too much grease or need longer cooking time.
Solution: Use pre-cooked kielbasa or smoked sausage to ensure proper cooking and flavor balance.

Serving and Pairing Suggestions

This casserole is satisfying on its own, but here are a few ways to elevate the experience:

– Serve with a slice of crusty rye or sourdough bread to soak up the juices.

– Pair with a crisp green salad with vinegar-based dressing to balance the richness.

– A dollop of whole grain mustard or sour cream on the side adds a zesty touch.

– Enjoy it as a main course or serve smaller portions as a side dish at a buffet or potluck.

Storage and Reheating Tips

Refrigerate leftovers in an airtight container for up to 4 days.

Freeze in individual portions for up to 2 months. Wrap tightly in foil or freezer-safe containers.

Reheat in the oven at 325°F, covered, for 15–20 minutes, or until warmed through.

Microwave individual servings with a splash of water and cover loosely—heat in 30-second intervals until hot.

FAQs

1. Can I use brown rice instead of white?
Brown rice takes longer to cook and may need more liquid. Parboil the brown rice first or extend baking time by 15–20 minutes with additional water.

2. What kind of sausage works best?
Smoked kielbasa is ideal, but turkey sausage or plant-based alternatives also work if pre-cooked.

3. Can I make this ahead of time?
Yes! Assemble the casserole, cover, and refrigerate up to 24 hours. Add an extra 10 minutes to the baking time if cold.

4. My rice didn’t cook through—what went wrong?
It’s likely the casserole was underbaked or lacked moisture. Cover it back up, add a few tablespoons of hot water, and return to the oven for 10–15 minutes.

5. Is this dish gluten-free?
It can be if you use a gluten-free tomato soup. Always check ingredient labels to be sure.

Tips & Tricks

Let the casserole rest before serving—it improves the texture and keeps the layers intact.

If your sauerkraut is too tangy, rinse it lightly before draining.

Add a dash of paprika or caraway seeds for extra depth of flavor.

For extra richness, stir in a handful of shredded cheddar or Swiss cheese on top before baking uncovered for the last 10 minutes.

Recipe Variations

Spicy Polish Twist
Use spicy kielbasa and add a pinch of red pepper flakes to the tomato soup mix. Top with shredded pepper jack cheese before baking uncovered for the last 10 minutes.

Vegetarian Version
Swap sausage for sautéed mushrooms and chopped roasted red peppers. Use vegetable broth instead of tomato soup for a lighter flavor profile.

German-Inspired Casserole
Add 1 tablespoon of stone-ground mustard and a teaspoon of caraway seeds to the soup mixture. Top with toasted rye breadcrumbs for texture.

Creamy Comfort Style
Replace tomato soup with a can of cream of mushroom or cream of celery soup for a creamier twist. Add shredded Swiss cheese before baking.
