Ingredients You’ll Need

Simple, everyday ingredients truly shine in this Crockpot Cowboy Casserole, each bringing color, richness, and that irresistible homestyle goodness. Here’s how every component plays a role in delivering both flavor and comfort!

• Olive Oil: Adds a subtle richness and helps brown the sausage and onions to perfection.
• Ground Italian Sausage (mild or hot): The main source of savory, meaty flavor. Choose your preferred spice level for a custom kick!
• Yellow Onion: Caramelizes with the sausage for a natural sweetness and depth of flavor.
• Salt & Pepper: Essential for seasoning, balancing all the other robust elements.
• Baby Red Potatoes (unpeeled): Their creamy texture holds up beautifully in the slow cooker, and the skins add color and nutrients.
• Green Bell Pepper: Bright, slightly sweet, and brings pretty pops of green to the casserole.
• Kidney Beans: Protein-packed and hearty, they soak up all those zesty flavors as they cook.
• Frozen Corn: Sweet kernels that burst with juiciness in every bite—no need to thaw ahead!
• Fire-Roasted Diced Tomatoes: The fire-roasting adds a subtle smoky note and a punch of tomato flavor.
• Minced Garlic: Just the right amount to wake up the whole dish with aromatic depth.
• Chili Powder: Offers gentle warmth and a touch of Southwestern flair without overpowering spice.
• Colby Jack Cheese (add later): Melts irresistibly on top, giving you gooey, cheesy pull in every serving.
• Fresh Cilantro & Sour Cream (optional): Bright, cool toppings that add a finishing touch of freshness and tang.

Variations

The beauty of Crockpot Cowboy Casserole is how effortlessly you can switch things up to suit whatever’s in your fridge (or your mood!). Here are some fun twists and swaps to try.

• Spicy Southwest: Swap in hot Italian sausage and add extra chili powder or jalapeños for bold, spicy flair.
• Veggie-Loaded: Double up on bell peppers, toss in some zucchini or carrots, or use black beans for a fiber boost.
• Cheesy Ranch: Mix a ranch seasoning packet into the potatoes or top with shredded cheddar for a tangy, herby twist.
• Turkey or Chicken Cowboy Casserole: Replace the sausage with ground turkey or rotisserie chicken for a lighter version.

How to Make Crockpot Cowboy Casserole

Step 1: Brown the Sausage & Onions

In a large skillet, heat the olive oil over high heat. Once shimmering, add the ground Italian sausage and diced onion. Brown and crumble the sausage, letting the onion go soft and caramelize. This step is key—it layers in deep flavor and gives the dish that irresistible savory backbone!

Step 2: Load Up the Crockpot

Transfer the sausage and onion mixture to your Crockpot. Thinly slice the baby red potatoes (leave those pretty skins on!), chop the green bell pepper, and drain and rinse your kidney beans. Add all these veggies, plus the frozen corn, fire-roasted diced tomatoes (don’t drain), minced garlic, and chili powder directly on top. Stir everything gently to combine, then press it down into an even layer for even cooking.

Step 3: Slow Cook Until Perfect

Cover and let your Crockpot Cowboy Casserole cook on HIGH for 2–4 hours, or on LOW for 4–6 hours. You’ll know it’s ready when the potatoes are melt-in-your-mouth tender and your kitchen is full of the most mouthwatering aroma. Give it a gentle stir and taste to adjust salt and pepper as needed.

Step 4: Add the Cheesy Finish

Sprinkle a generous layer of shredded Colby Jack cheese evenly over the casserole. Cover again and let the cheese melt into gooey, golden goodness—about 5–10 minutes. Optional: garnish with fresh cilantro and a dollop of sour cream just before serving for extra flair!

How to Serve Crockpot Cowboy Casserole

Garnishes

The right garnish takes this casserole from comforting to company-worthy. Try a sprinkle of fresh cilantro for brightness, a generous spoonful of sour cream for creaminess, or a dash of diced green onions for subtle crunch and color. For an extra Tex-Mex vibe, chopped tomatoes or sliced jalapeños make an amazing finishing touch!

Side Dishes

This hearty Crockpot Cowboy Casserole truly stands on its own, but it also loves a little company. Pair it with a simple green salad, a warm skillet cornbread, or even a pile of tortilla chips for scooping up every cheesy bite. Classic baked beans or steamed broccoli also fit the bill perfectly!

Creative Ways to Present

Think beyond the bowl! Spoon the casserole into mini cast iron skillets for individual servings, load it into baked potato halves for a fun “cowboy potato” night, or serve over a bed of rice for Tex-Mex comfort. If you’re hosting a potluck, keep it warm in the slow cooker—everyone can help themselves.

Make Ahead and Storage

Storing Leftovers

Allow your Crockpot Cowboy Casserole to cool completely before transferring to an airtight container. It stays fresh in the fridge for up to 3–4 days, making it perfect for meal prep or easy lunches all week long.

Freezing

This casserole is freezer-friendly! Once cooled, portion into freezer-safe containers or sealable bags. Freeze for up to 2–3 months. For best texture, thaw overnight in the fridge before reheating—this keeps everything creamy and delicious.

Reheating

To reheat, simply microwave individual portions (adding a splash of water if needed to loosen) or warm larger servings gently in the oven at 325°F, covered, until hot. The flavors deepen overnight—leftovers are always a treat!
