How to make Cowboy Casserole:

Ingredients:
- Oil – I typically use Olive Oil but any oil you have on hand will work.
- Onion – diced fine for easy eating and cooking.
- Ground Beef – I used a lean 90/10 ground beef.
- Seasoning Salt – a tad more flavorful than regular salt.
- Black Pepper
- Cream of Mushroom Soup
- Rotel – drained if there is a lot of juice.
- Corn – can of corn drained.
- Milk – I used 2% milk for this recipe.
- Colby Jack Cheese – I used a bag of shredded Colby Jack Cheese for this recipe.
- Tater Tots – frozen.

Directions:
Step One – Preheat the oven to 375 degrees and prepare a 9×13 casserole pan with cooking spray.
Step Two – In a large skillet over medium heat, sauté onions in oil until translucent, then add in beef and cook until no longer pink.

Step Three – When the meat is done remove any remaining oils from the pan and then add spices.
Step Four – Next stir in the corn, Rotel, and cream of mushroom soup. Then stir in the milk.

Step Five – Add the mixture to the casserole pan and spread out evenly. Then sprinkle 1 cup of the cheese on top.

Step Six – Last line up the tater tots on top of the cheese until completely covered.
Recipe Tip
Cheddar cheese works great in this recipe as well.

Baking Directions:
Step Seven – Bake for 40-45 minutes until bubbly and the tater tots are crispy. Sprinkle the remaining cheese on top and bake for a few more minutes to melt.

Pro Tips:
For a crispy topping, sprinkle crushed crackers or fried onions over the cheese before baking.
Let the casserole rest before serving so it sets up nicely.
Add a pinch of garlic powder or paprika for extra flavor.
Serve with a simple green salad or cornbread for a complete meal.
