How to Make Cheesy Beef & French Fry Casserole
1. Preheat the Oven
Preheat your oven to 425°F (220°C).
Lightly grease a 9×13-inch baking dish.
2. Give the Fries a Head Start
Arrange the frozen French fries on a large baking sheet.
Bake for approximately 12–15 minutes.
They do not need to become fully crisp yet.
This head start helps prevent the fries from becoming soggy once they are added to the casserole.
3. Heat the Skillet
While the fries bake, place a large skillet over medium-high heat.
Add olive oil if your beef is especially lean.
4. Brown the Ground Beef
Add the ground beef.
Break it into small crumbles.
Cook for approximately 6–8 minutes, until browned.
Ground beef should reach 160°F (71°C).
5. Add the Onion
Add the diced onion.
Cook for approximately 3–4 minutes, until softened.
6. Add the Garlic
Stir in the minced garlic.
Cook for approximately 30–60 seconds, just until fragrant.
7. Drain Excess Grease
If necessary, carefully drain most of the fat from the skillet.
8. Add Tomato Paste
Stir in the tomato paste.
Cook for approximately 1–2 minutes.
9. Add the Condiments
Stir in:
- Worcestershire sauce
- Ketchup
- Mustard
10. Season the Beef
Add:
- Garlic powder
- Onion powder
- Smoked paprika
- Salt
- Black pepper
- Red pepper flakes, if using
Stir well.
11. Cook Until Flavorful
Continue cooking for approximately 2 minutes.
The mixture should be savory and relatively dry rather than watery.
12. Transfer the Beef
Spread the cooked beef evenly across the bottom of the prepared baking dish.
13. Make the Cheese Sauce
Place a medium saucepan over medium heat.
Add the butter.
14. Add the Flour
Once the butter melts, sprinkle in the flour.
Whisk continuously for approximately 1–2 minutes.
15. Add Beef Broth
Slowly pour in the beef broth while whisking.
Continue whisking until smooth.
16. Add Milk
Gradually pour in the milk.
Whisk until combined.
17. Add Seasonings
Stir in:
- Dijon mustard
- Garlic powder
- Onion powder
- Black pepper
18. Simmer
Cook over medium-low heat for approximately 3–5 minutes.
The sauce should begin to thicken.
19. Add Sour Cream
Reduce the heat to low.
Stir in the sour cream until smooth.
20. Add Cheddar
Gradually add the cheddar.
Stir until completely melted.
Avoid boiling aggressively after the cheese is added.
21. Check the Sauce
The sauce should be creamy and pourable.
If it becomes too thick, add a splash of milk or beef broth.
22. Pour Over the Beef
Pour the cheese sauce evenly over the ground beef.
23. Add the First Cheese Layer
Sprinkle approximately half of the cheddar and mozzarella over the sauce.
24. Add the French Fries
Arrange the partially baked fries over the top.
You can create a neat single layer or scatter them more casually.
25. Add Remaining Cheese
Sprinkle the remaining cheddar and mozzarella over the fries.
26. Add Parmesan
Finish with Parmesan if using.
27. Bake
Reduce the oven temperature to 400°F (200°C).
Bake uncovered for approximately 20–25 minutes.
28. Check the Fries
The fries should be golden around the edges and the cheese should be bubbling.
29. Broil for Extra Crispness
For an especially golden topping, broil for approximately 1–2 minutes.
Watch carefully.
30. Add Bacon
If using bacon, sprinkle it over the casserole after baking.
31. Rest
Let the casserole rest for approximately 5–10 minutes.
32. Add Fresh Toppings
