Plus, it's easily customizable to suit your own preferences. So, gather your ingredients, preheat your oven, and get ready to experience the ultimate comfort food. Let's make some Cowboy Beef Potato Casserole!

Ingredients:
- 2 lbs Ground Beef
- 1 large Onion, chopped
- 2 cloves Garlic, minced
- 1 (10.75 oz) can Condensed Cream of Mushroom Soup
- 1 (10.75 oz) can Condensed Cream of Celery Soup
- 1 (4 oz) can Diced Green Chilies, undrained
- 1 cup Sour Cream
- 1 cup Shredded Cheddar Cheese, divided (reserve ½ cup for topping)
- 1 tsp Garlic Powder
- 1 tsp Onion Powder
- 1/2 tsp Black Pepper
- Salt to taste
- 3 lbs Russet Potatoes, peeled and cubed
- 1/2 cup Milk
- 1/4 cup Butter, melted
- 1/4 cup Crispy Fried Onions (for topping)
- Optional: Chopped fresh parsley, for garnish
Preparing the Beef Mixture:
- Brown the Ground Beef: In a large skillet over medium-high heat, brown the ground beef. Break it up with a spoon as it cooks. Drain off any excess grease. This step is crucial for preventing a greasy casserole.
- Sauté the Aromatics: Add the chopped onion to the skillet with the browned beef. Cook until the onion is softened and translucent, about 5-7 minutes. Then, add the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic, as it can become bitter.
- Combine the Soup and Spices: Stir in the cream of mushroom soup, cream of celery soup, diced green chilies (undrained), sour cream, garlic powder, onion powder, and black pepper. Mix well to combine all the ingredients. The green chilies add a nice kick, but you can adjust the amount to your preference.
- Add Cheese and Season: Add ½ cup of the shredded cheddar cheese to the beef mixture. Stir until the cheese is melted and the mixture is creamy. Season with salt to taste. Remember that the soup already contains salt, so start with a small amount and adjust as needed.
Preparing the Potatoes:
- Boil the Potatoes: Place the peeled and cubed potatoes in a large pot. Cover with cold water and add a pinch of salt. Bring to a boil over high heat, then reduce the heat to medium and simmer until the potatoes are tender, about 15-20 minutes. You should be able to easily pierce them with a fork.
- Drain the Potatoes: Once the potatoes are tender, drain them well in a colander. Make sure to remove as much water as possible to prevent a watery casserole.
- Mash the Potatoes: Return the drained potatoes to the pot. Add the milk and melted butter. Mash the potatoes until smooth and creamy. You can use a potato masher or an electric mixer for this step. If using an electric mixer, be careful not to overmix, as this can make the potatoes gummy.
- Season the Potatoes: Season the mashed potatoes with salt and pepper to taste. Adjust the amount of milk and butter to achieve your desired consistency. Some people prefer their mashed potatoes thicker, while others prefer them creamier.
Assembling the Casserole:
- Preheat the Oven: Preheat your oven to 350°F (175°C). This ensures that the casserole cooks evenly.
- Grease the Baking Dish: Lightly grease a 9x13 inch baking dish with cooking spray or butter. This will prevent the casserole from sticking to the dish.
- Layer the Ingredients: Spread the beef mixture evenly in the prepared baking dish. This forms the base of the casserole.
- Top with Mashed Potatoes: Carefully spread the mashed potatoes evenly over the beef mixture. Use a spatula to smooth the surface.
- Add Cheese and Onions: Sprinkle the remaining ½ cup of shredded cheddar cheese evenly over the mashed potatoes. Then, sprinkle the crispy fried onions over the cheese. The crispy fried onions add a delicious crunch and flavor to the casserole.
Baking the Casserole:
- Bake the Casserole: Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly and the casserole is heated through. The top should be lightly golden brown.
- Let it Rest: Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the casserole to set slightly and makes it easier to slice.
- Garnish and Serve: Garnish with chopped fresh parsley, if desired. Serve hot and enjoy! This casserole is a hearty and satisfying meal that is perfect for a weeknight dinner or a potluck.
Tips and Variations:
- Add Vegetables: Feel free to add other vegetables to the beef mixture, such as diced bell peppers, corn, or peas.
- Spice it Up: For a spicier casserole, add a pinch of cayenne pepper or a dash of hot sauce to the beef mixture.
- Use Different Cheese: You can use different types of cheese, such as Monterey Jack, Pepper Jack, or Colby Jack.
- Make it Ahead: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Add about 10-15 minutes to the baking time if baking from cold.
- Freeze it: This casserole can also be frozen for up to 3 months. Thaw it overnight in the refrigerator before baking.
- Healthier Option: Use lean ground beef or ground turkey to reduce the fat content. You can also use low-fat sour cream and cheese. Consider using cauliflower mash instead of potato mash for a lower carb option.
- Cream Cheese Addition: For an extra creamy potato layer, mix 4 ounces of softened cream cheese into the mashed potatoes. This adds richness and tang.
- Bacon Bits: Sprinkle cooked bacon bits on top of the casserole along with the cheese and crispy fried onions for added flavor and texture.
- Gravy Boost: For a richer flavor, stir in 1/2 cup of beef gravy into the beef mixture.
- Slow Cooker Adaptation: Brown the beef and prepare the potato topping as directed. Layer the beef mixture in the bottom of a slow cooker, top with the potatoes, cheese, and onions. Cook on low for 4-6 hours or on high for 2-3 hours, or until heated through.
Serving Suggestions:
This Cowboy Beef Potato Casserole is a complete meal on its own, but it also pairs well with a simple side salad or steamed vegetables. Consider serving it with:
- Green Salad with a vinaigrette dressing
- Steamed Broccoli or Green Beans
- Corn on the Cob
- Dinner Rolls
