Why This Cheesy Beef & Potato Jalapeño Casserole Recipe Works
This casserole is the ultimate crowd-pleaser for so many reasons. First, it’s made with simple, affordable ingredients that you probably already have in your kitchen. Ground beef, potatoes, jalapeños, and a few pantry staples come together to create a dish that’s both comforting and crave-worthy.
But the real secret is in the creamy, cheesy sauce that coats every bite. I use a blend of melty cheddar and tangy sour cream to create a sauce that’s rich, velvety, and perfectly balanced with the heat from the jalapeños. It’s like a hug for your tastebuds!
And let’s not forget about that crispy, golden-brown topping. By sprinkling shredded cheese and crushed tortilla chips over the top, you get a delightful contrast of textures in every forkful. It’s the perfect way to elevate this humble casserole into something truly special.
Ingredients for Cheesy Beef & Potato Jalapeño Casserole
- 1 lb ground beef
- 1 onion, diced
- 3 cloves garlic, minced
- 2 lbs russet potatoes, peeled and cubed
- 2 jalapeños, seeded and diced
- 2 cups shredded cheddar cheese, divided
- 1 cup sour cream
- 1 can (10.5 oz) cream of mushroom soup
- 1 tsp chili powder
- 1 tsp cumin
- Salt and pepper to taste
- 1 cup crushed tortilla chips
Diana’s Tip: For the best texture, make sure to cube the potatoes into small, evenly-sized pieces. This will help them cook through thoroughly in the casserole.
Optional Add-Ins and Variations
One of the things I love most about this Cheesy Beef & Potato Jalapeño Casserole is how versatile it is. Here are a few ways you can customize it to your liking:
- Spice it up: If you really love the heat, feel free to add an extra jalapeño or two. You can also swap out the mild chili powder for a hotter variety.
- Make it meaty: In addition to the ground beef, you could also add in some crumbled bacon or diced ham for even more savory flavor.
- Go veggie-forward: Sauté some bell peppers, zucchini, or corn along with the onions and garlic for extra veggies.
- Switch up the cheese: While cheddar is my personal favorite, you could also try pepper jack, Monterey jack, or a Mexican cheese blend.
- Spice it up for the holidays: Add a festive twist by stirring in some chopped fresh rosemary or thyme for a cozy, Christmas-y flavor.
How to Make Cheesy Beef & Potato Jalapeño Casserole
- Preheat your oven to 375°F (190°C).
- In a large skillet over medium-high heat, cook the ground beef until browned and crumbled, 5-7 minutes. Drain any excess fat.
- Diana’s Tip: To prevent the beef from becoming tough or dry, be sure not to overcrowd the pan. Cook it in batches if needed.
- Add the diced onion and minced garlic to the skillet. Sauté for 2-3 minutes, until the onion is translucent.
- Stir in the cubed potatoes, diced jalapeños, 1 cup of the shredded cheddar cheese, sour cream, cream of mushroom soup, chili powder, and cumin. Season with salt and pepper to taste.
- Transfer the mixture to a 9×13-inch baking dish. Sprinkle the remaining 1 cup of shredded cheddar cheese and the crushed tortilla chips over the top.
- Bake for 30-35 minutes, or until the potatoes are tender and the topping is golden brown and crispy.
- What I Messed Up At First: When I first made this casserole, I didn’t fully cook the potatoes before baking. They ended up a bit undercooked in the final dish. Now I make sure to sauté them with the beef and onions until they’re just starting to soften.
Common Mistakes to Avoid
To ensure your Cheesy Beef & Potato Jalapeño Casserole turns out perfectly every time, here are a few common mistakes to steer clear of:
- Overcrowding the pan: As I mentioned before, be sure not to overcrowd the skillet when browning the beef. This can cause the meat to steam rather than brown, resulting in a less flavorful dish.
- Undercooked potatoes: Make sure to sauté the potato cubes until they’re just starting to soften before assembling the casserole. This ensures they’ll be tender and cooked through in the final bake.
- Skimping on the cheese: The creamy, cheesy sauce is what really makes this casserole shine. Don’t be afraid to be generous with the cheddar cheese – it’s the star of the show!
- Forgetting the tortilla chip topping: The crunchy, golden-brown topping is an absolute must. It adds the perfect textural contrast to the soft, creamy casserole.
My Tested Substitutions
While this Cheesy Beef & Potato Jalapeño Casserole is pretty darn perfect as-is, I know everyone has their own preferences and dietary needs. Here are a few ingredient swaps that I’ve tested and approved:
- Ground turkey or chicken: For a leaner protein option, you can easily substitute ground turkey or chicken for the beef.
- Gluten-free cream of mushroom: If you need to make this casserole gluten-free, just swap in a gluten-free cream of mushroom soup.
- Greek yogurt: In place of the sour cream, you can use an equal amount of plain Greek yogurt for a tangier flavor.
- Crushed pork rinds: For a low-carb topping, use crushed pork rinds instead of the tortilla chips.

How to Customize This Cheesy Beef & Potato Jalapeño Casserole
One of the best things about this recipe is how easy it is to customize to your specific tastes and dietary needs. Here are a few ideas to get you started:
- Make it keto-friendly: Swap the potatoes for cauliflower florets and use a low-carb cream of mushroom soup to make this casserole keto-approved.
- Turn it into a breakfast dish: Top the casserole with a few cracked eggs before baking for a hearty, protein-packed breakfast.
- Feed a crowd: Double the recipe and bake it in a large 9×13-inch pan to serve a hungry group.
- Meal prep it: Assemble the casserole ahead of time, then just pop it in the oven when you’re ready to eat. It reheats beautifully!
