Ingredients

For the Savory Meat Layer:

1 ½ lbs (680g) lean ground beef (85/15 or 90/10)
1 medium yellow onion, finely diced
3 cloves garlic, minced
1 teaspoon kosher salt, divided
½ teaspoon black pepper, divided
1 tablespoon Worcestershire sauce
1 tablespoon tomato paste

For the Vegetable Mix:

1 (10.5 oz) can condensed cream of mushroom soup (or cream of celery, or onion)
½ cup sour cream
½ cup beef broth or milk
2 cups frozen mixed vegetables (classic corn, peas, carrots, and green beans blend), thawed

For the Cheese & Topping:

2 cups (8 oz) shredded sharp cheddar cheese, divided
1 cup (4 oz) shredded Monterey Jack or mozzarella cheese
1 (28-32 oz) bag frozen crispy French fries (thin cut or classic crinkle-cut work best)
¼ teaspoon smoked paprika or garlic powder (for dusting fries)
2 tablespoons chopped fresh parsley or chives, for garnish (optional)

For Serving (Optional):

Ketchup, ranch dressing, or fry sauce
Extra sour cream
Pickled jalapeños

Equipment

9×13 inch (3-quart) baking dish
Large skillet
Medium mixing bowl
Wooden spoon or spatula
Measuring cups and spoons
Aluminum foil

Instructions

Part 1: Building the Hearty Base (Time: 15 minutes | Intensity: Medium)

Preheat & Prep: Position a rack in the center of your oven and preheat to 400°F (200°C). Lightly grease your 9×13 inch baking dish. Take the French fries out of the freezer to begin thawing slightly—this helps them crisp better.
Brown the Beef: In a large skillet over medium-high heat, add the ground beef, diced onion, and minced garlic. Season with ½ teaspoon of the salt and ¼ teaspoon of the black pepper. Cook, breaking up the meat with a wooden spoon, until the beef is no longer pink and the onions are softened, about 7-8 minutes. Drain any excess fat.
Develop Flavor: Stir in the Worcestershire sauce and tomato paste. Cook for 1-2 more minutes, allowing the tomato paste to darken slightly and coat the meat. This builds a rich, savory depth. Remove from heat.

Part 2: The Creamy, Cheesy Bind (Time: 5 minutes | Intensity: Low)

Make the Creamy Sauce: In your medium mixing bowl, whisk together the condensed cream of mushroom soup, sour cream, and beef broth (or milk) until smooth.
Combine Everything: Pour the creamy soup mixture into the skillet with the cooked beef. Add the thawed mixed vegetables, 1 cup of the shredded cheddar cheese, and all of the Monterey Jack cheese. Stir until everything is evenly combined and coated in the sauce.

Part 3: The Layered Assembly (Time: 5 minutes | Intensity: Low)

Transfer to Dish: Pour the entire meat and vegetable mixture into the prepared baking dish. Spread it into a smooth, even layer.
Cheese Barrier: Sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top of the meat layer. This creates a delicious melted barrier that helps prevent the fries from sinking.
The Iconic Topping: Arrange the partially thawed French fries in a single, tightly packed layer over the cheese, covering the surface completely. For extra flavor, lightly sprinkle the fries with the remaining ½ teaspoon salt, ¼ teaspoon pepper, and a dusting of smoked paprika or garlic powder.

Part 4: The Bake to Crispy-Creamy Perfection (Time: 45 minutes | Intensity: Passive)

Bake Covered (The Steaming Phase): Loosely tent the baking dish with aluminum foil. Bake for 25 minutes. This covered phase steams the fries and ensures the casserole heats through completely without the fries burning.
Bake Uncovered (The Crisping Phase): Carefully remove the foil. Continue baking, uncovered, for another 18-22 minutes, or until the French fries are deep golden brown and crispy, and the cheese is bubbling vigorously around the edges of the dish.
The Crucial Rest: Once out of the oven, let the casserole rest on a wire rack for 8-10 minutes. This allows the bubbling, creamy filling to settle and thicken slightly, making it much easier to scoop out clean servings that hold their shape.

Serving & The Feast

Garnish & Present: Sprinkle with fresh parsley or chives for a pop of color and freshness.
Serve Generously: Use a large, sturdy spatula or serving spoon to dig down through the crispy fry roof and into the creamy beef layer beneath. Ensure each plate gets a perfect cross-section of crispy topping and savory filling.
Accompaniments: Serve directly from the dish at the table. Place bowls of ketchup, ranch, or your favorite fry sauce on the side for dipping. A simple green salad or some tangy coleslaw is the perfect fresh contrast to this rich bake.

Recipe Notes & Pro-Tips for Success

Fry Philosophy: Using frozen fries is not only convenient but ideal. Their structure holds up to baking better than homemade fries would in this application. Thin-cut or crinkle-cut fries provide the best crispy-to-creamy ratio.
Meat Variations: Ground turkey, chicken, or a plant-based ground meat substitute work perfectly here. For a “cheeseburger” vibe, add 1 teaspoon of yellow mustard and ¼ cup of diced dill pickles to the meat mixture.
Vegetable Flexibility: Use any frozen veggie blend you like. A California blend (broccoli, cauliflower, carrots) or even just corn and peas are great options. For fresh vegetables, chop them small and sauté with the onions until tender.
Soup Swap: Cream of onion, celery, or cheddar soup can be used in place of mushroom. For a from-scratch version, make a simple white sauce (2 tbsp butter, 2 tbsp flour, 1 ¼ cups milk) and season it well.
Make-Ahead Magic: Assemble the casserole completely through Step 3 (topping with the first cheese layer, but do not add the fries). Cover and refrigerate for up to 24 hours. When ready to bake, add the frozen fries on top and bake as directed, adding 5-10 minutes to the covered bake time.
Leftovers & Reheating: Store leftovers covered in the fridge for up to 3 days. Reheat portions in an air fryer or toaster oven to restore the fries’ crispiness. The microwave will soften the fries but is still effective for a quick meal.
