Ingredients
Below is a concise list of the ingredients you need. See the recipe card for exact quantities.
- Lean ground beef – Use lean beef to avoid a greasy casserole while keeping flavor.
- Frozen mixed vegetables – A blend with green beans, corn, carrots, peas, and onions works well, but use your preferred mix.
- Cream of soup – Any variety (mushroom, chicken, or celery) will work; choose a gluten-free option if needed.
- Sour cream – Regular or light sour cream adds creaminess. A plant-based alternative can be used for dairy-free needs.
- Shredded cheese – Cheddar is great for sharp flavor; mix cheeses or add pepper jack for a spicy kick.
- Frozen tater tots – They create the crispy, golden topping that makes this casserole special.
- Salt and pepper – To taste.
How to Make Cowboy Casserole
This casserole comes together quickly with a large skillet and a 9×13 baking dish. Follow these simple steps.
Make the filling
Preheat the oven to 400°F. In a large skillet over medium-high heat, cook the ground beef, breaking it into crumbles. When browned, drain off any excess grease. Reduce the heat to low and add the frozen vegetables, cream of soup, and sour cream. Stir until everything becomes a smooth, creamy sauce, then add half the cheese and stir until melted. Season with salt and pepper to taste.
Assemble and bake
Spray a 9×13 baking dish with oil. Transfer the beef and vegetable mixture to the dish and spread it evenly. Sprinkle the remaining cheese over the top, then arrange the frozen tater tots in a single layer on top of the cheese. Bake in the preheated oven for 30–40 minutes, or until the tater tots are golden and crispy.
Serve
Let the casserole rest about 5 minutes after baking so the filling firms up slightly. Serve as a complete meal—no side dishes required—or pair with a simple salad or warm biscuits for extra comfort.
Storage and reheating
Cool leftovers completely, then store in an airtight container in the refrigerator for 3–4 days. To reheat, microwave individual portions at reduced power in 60-second intervals (the topping will lose crispness), or re-crisp in an air fryer at 350°F for 3–5 minutes or in the oven at 350°F for 8–12 minutes.
Freezing tips
This casserole freezes well and makes a great make-ahead meal. For best results, assemble the casserole and bake it before freezing. Cool, cover tightly, and freeze. When ready to enjoy, thaw in the refrigerator and bake according to the instructions, adding 5–10 minutes to the baking time if needed. If the tater tots brown too quickly, tent the dish with foil.
