Ingredients You’ll Need
This Southwestern Potato Casserole Recipe relies on a handful of simple ingredients that work together beautifully to create a balance of freshness, spice, and creamy texture. Each component has its own role in making sure your dish is flavorful, colorful, and satisfying.
- Frozen diced potatoes (thawed): These are the hearty base of the casserole, bringing comforting texture and substance.
- Olive oil: Adds a smooth richness and helps soften the onions and peppers.
- Small onion (diced): Contributes sweet, aromatic depth to the flavor profile.
- Red and green bell peppers (diced): These vibrant veggies provide crunch and a pop of color that makes the dish inviting.

- Frozen corn: Sweet bursts that complement the savory spices perfectly.

How to Make Southwestern Potato Casserole Recipe
Step 1: Prep Your Oven and Vegetables
Start by preheating your oven to 375°F (190°C) and generously coating a 9×13-inch baking dish with nonstick spray to prevent sticking. Next, heat the olive oil in a large skillet over medium heat. Sauté the diced onion and both red and green bell peppers until they soften and release their fragrant sweetness, about 4 to 5 minutes. This step releases the natural sugars and deepens the flavor, making sure your casserole is bursting with fresh, vibrant taste.
Step 2: Combine the Ingredients
In a large mixing bowl, add your thawed diced potatoes along with the sautéed onions and bell peppers. Toss in the black beans, frozen corn, and drained diced tomatoes with green chilies. Now sprinkle in the cumin, chili powder, smoked paprika, garlic powder, salt, and pepper. Stir everything together until fully combined. This mixture will be packed with robust Southwestern flavors, just waiting to meld during baking.
Step 3: Add Cheese and Transfer to Baking Dish
Stir 1 cup of the shredded Mexican blend cheese into your mixture for that luscious, melty texture baked right inside. Then, carefully spread the mixture evenly into your prepared baking dish. Finally, sprinkle the remaining 1/2 cup of cheese on top to create a golden, bubbly crust that’s simply irresistible.
Step 4: Bake and Enjoy
Place the casserole in your preheated oven and bake for 35 to 40 minutes. You’ll know it’s ready when it’s heated through and the cheese has melted into a bubbly, golden delight. Once out of the oven, let it cool for a few minutes before adding a sprinkle of fresh chopped cilantro if you like — this adds a lovely herbaceous freshness that perfectly balances the rich flavors.
How to Serve Southwestern Potato Casserole Recipe
Garnishes
Fresh cilantro is a classic garnish that adds zest and freshness to the casserole. If you’re feeling adventurous, top with sliced jalapeños for an extra kick or dollop with creamy avocado or cool Greek yogurt to contrast the spiciness and add richness.
Side Dishes
This dish shines both as a main and a side. Pair your Southwestern Potato Casserole Recipe with a crisp green salad or Mexican street corn for a well-rounded meal. It also complements grilled meats or roasted vegetables beautifully, making it versatile for any occasion.
Creative Ways to Present
Serve portions in individual ramekins for a fun, personalized presentation. You can also scoop the casserole onto warm tortillas for a hearty, rustic Southwestern breakfast or lunch option. And don’t forget to add a squeeze of lime juice or a drizzle of your favorite salsa for an added punch.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftover Southwestern Potato Casserole Recipe tightly with plastic wrap or transfer it to an airtight container. It stays fresh in the fridge for 3 to 4 days, making it a perfect make-ahead meal for busy weeknights.
Freezing
You can freeze this casserole for up to 2 months. Wrap it well in foil and plastic wrap or use a freezer-safe container to protect against freezer burn. For best texture, consider freezing before baking and then bake straight from frozen — just add some extra time to the cooking process.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through to maintain the crispy cheese topping. Alternatively, microwave individual servings for a quick option but keep in mind the texture might be softer.
FAQs
Can I make this Southwestern Potato Casserole Recipe vegan?
