What You’ll Need

- 1/2 Onion, finely diced: Adds sweetness and depth to the meaty foundation.
- 1 tsp Garlic Powder: Enhances the savory notes and adds a delightful aroma.
- Salt and Pepper to taste: Essential seasonings to bring out the best flavors in your ground beef.
- 1 cup Cheddar Cheese, shredded: The star of the show! Sharp cheddar is ideal, but you can experiment with other varieties.
- 1 can (10.5 oz) Cream of Mushroom Soup: Creates a rich and creamy sauce that binds everything together beautifully.
- 1/2 cup Milk: Adds creaminess and helps to thin out the soup for a smoother consistency.
- 1/4 cup Ketchup: Provides a touch of sweetness and tang.
- 1/4 cup Yellow Mustard: Adds a sharp and slightly spicy counterpoint to the ketchup.
- 1 bag (32 oz) Frozen French Fries: The crispy, salty foundation of this heavenly casserole. Choose your favorite brand!
- Optional Toppings: Diced pickles, chopped tomatoes, lettuce, or extra cheese for a personalized touch.
Step-by-Step Instructions
Let’s get cooking! This recipe is easier than you think:
- Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish. This ensures easy cleanup and prevents sticking.
- Brown the ground beef: In a large skillet over medium-high heat, brown the ground beef, breaking it up with a spoon. Drain off any excess grease. Tip: For extra flavor, add a pinch of onion powder along with the garlic powder.
- Sauté the onion: Add the diced onion to the skillet and cook until softened, about 3-5 minutes. Stir in the garlic powder, salt, and pepper. Season generously – your taste buds will appreciate it!
- Prepare the cheese sauce: In a medium bowl, whisk together the cream of mushroom soup, milk, ketchup, and mustard until smooth and creamy. Tip: For a smoother sauce, use an immersion blender to remove any lumps from the soup.
- Assemble the casserole: Spread half of the French fries in the prepared baking dish. Top with the ground beef mixture, then pour the cheese sauce evenly over the beef. Sprinkle with the shredded cheddar cheese. Tip: Don’t overload the casserole with cheese; it can become too heavy.
- Add the remaining fries: Arrange the remaining French fries on top of the cheese layer. You can slightly overlap them for a fuller look.
- Bake: Bake for 25-30 minutes, or until the casserole is bubbly and the French fries are golden brown and crispy. Tip: For extra crispy fries, broil the casserole for the last 2-3 minutes, watching carefully to prevent burning.
- Rest and serve: Let the casserole rest for 5-10 minutes before serving. This allows the cheese to set slightly and prevents a messy serving experience.
- Garnish and enjoy: Garnish with your favorite toppings – diced pickles, chopped tomatoes, lettuce, or extra cheese – and serve hot.
Tips for Success
Here are a few tips to ensure your Cheeseburger French Fry Casserole turns out perfectly every time:
Don’t overcook the ground beef; it should be browned, not dry. Make sure to drain off excess grease to prevent a soggy casserole. Use freshly shredded cheddar cheese for the best melt. If using pre-shredded cheese, add a tablespoon of cornstarch to the cheese sauce to help it melt smoothly. Don’t be afraid to experiment with different types of cheese. Monterey Jack or a blend of cheddar and pepper jack would also be delicious. For extra flavor, add a tablespoon of Worcestershire sauce to the ground beef mixture. And finally, let the casserole rest for a few minutes before serving to prevent a messy and uneven distribution of ingredients.
Variations to Try
Feeling adventurous? Here are some delicious variations to try:
Spicy Cheeseburger Casserole: Add a pinch of cayenne pepper or a dash of your favorite hot sauce to the ground beef mixture. Bacon Cheeseburger Casserole: Add 4-6 slices of cooked, crumbled bacon to the ground beef mixture. Vegetarian Version: Substitute the ground beef with 1 cup of cooked lentils or crumbled vegetarian sausage. Gluten-Free Option: Use gluten-free French fries. Gourmet Upgrade: Use truffle oil instead of regular olive oil to give it a sophisticated touch. Don’t hesitate to get creative and make it your own!
Storing and Reheating
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, you can either microwave individual portions for 1-2 minutes or bake the entire casserole in a preheated oven at 350°F (175°C) for 15-20 minutes, until heated through. Freezing is also an option. Allow the casserole to cool completely before placing it in a freezer-safe container. It will keep in the freezer for up to 2 months. To reheat from frozen, thaw overnight in the refrigerator, then bake as directed above.

Frequently Asked Questions
Q: Can I use fresh French fries instead of frozen? A: Yes, you can, but be aware that fresh fries will cook faster than frozen fries. You may need to reduce the baking time. Q: Can I substitute the cream of mushroom soup? A: Yes, you can use cream of chicken soup or even a homemade cheese sauce for a richer flavor. Q: How long can I keep leftovers? A: Leftovers should be stored in an airtight container in the refrigerator for up to 3 days. Q: Can I make this ahead of time? A: Yes, you can assemble the casserole the day before and bake it when ready. However, I recommend keeping the fries separate until you are ready to bake it in order to maintain their crispiness.
