Ground beef, tater tots, cheese, lettuce, tomatoes, pickles, and Big Mac sauce ingredients for casserole — Essential Ingredients for Big Mac Tater Tot Casserole

Ground Beef & Seasonings

Ground Beef: About 1-1.5 pounds. I usually go for 80/20 for flavor, but you can use leaner if you prefer.
Onion: One medium onion, diced.
Garlic: Two cloves, minced. (Because garlic makes everything better!)
Seasonings: Salt, pepper, garlic powder, onion powder. You can also add a pinch of smoked paprika for extra depth.

The Big Mac Sauce Secret

Mayonnaise: The base of our sauce.
Sweet Pickle Relish: Gotta have that signature tang!
Yellow Mustard: Just a touch for zing.
White Vinegar: Adds a little sharpness.
Garlic Powder, Onion Powder, Paprika: For that iconic Big Mac flavor.

Tater Tots & Cheese Essentials

Tater Tots: One bag (about 30 ounces). Frozen, ready to go!
Shredded Cheddar Cheese: Use any cheese you enjoy best but Cheddar adds great color and sharpness. An alternative could be yellow cheese.
Shredded Lettuce: For topping.
Diced Tomatoes: For topping.
Diced Pickles: For topping.

Step-by-Step Instructions

Okay, let’s get cooking! This is seriously so easy, even the kids can help out (Adams loves sprinkling the cheese!).

Prepping the Meat Layer

Brown the Beef: In a large skillet over medium-high heat, brown the ground beef. Break it up with a spoon as it cooks.
Add Aromatics: Once the beef is browned, drain off any excess grease. Add the diced onion and minced garlic to the skillet and cook until softened, about 5 minutes.
Season it Up: Season the beef mixture with salt, pepper, garlic powder, and onion powder. Stir well to combine.

Building the Casserole Layers

Sauce It: In a small bowl, whisk together the mayonnaise, sweet pickle relish, yellow mustard, white vinegar, garlic powder, onion powder, and paprika. This is our Big Mac sauce!
Layer Up: Spread half of the Big Mac sauce evenly over the bottom of a greased 9×13 inch baking dish.
Beef Time: Spread the seasoned ground beef mixture over the sauce.
Cheese Please: Sprinkle half of the shredded cheddar cheese over the beef.
Tot Time!: Arrange the frozen tater tots in a single layer over the cheese.
More Sauce: Drizzle the remaining Big Mac sauce over the tater tots.
Final Cheese Layer: Sprinkle the remaining cheddar cheese over the sauce.

Baking Tips for Crispy Tots

Bake Time: Bake in a preheated oven at 375°F (190°C) for 25-30 minutes, or until the tater tots are golden brown and crispy and the cheese is melted and bubbly.
Broiling (Optional): For extra crispy tots, broil for the last 1-2 minutes, keeping a close eye to prevent burning.
Garnish: Remove from the oven and let cool slightly. Top with shredded lettuce, diced tomatoes, and diced pickles.

Recipe Variations & Substitutions

Want to mix things up? No problem! Here are a few ideas to customize this big mac tater tot casserole to your liking:

Low-Calorie Options (Lean Beef, Light Cheese)

Lean Beef: Use ground turkey or extra-lean ground beef to reduce the fat content.
Trust me, folks. It cuts the calories without sacrificing good taste.
Light Cheese: Opt for reduced-fat cheddar cheese or a lighter cheese alternative.
Light Mayo: Use light mayonnaise to lighten up the Big Mac sauce.

Gluten-Free Adaptations

Gluten-Free Tater Tots: A lot of store-bought tater tots contain gluten. Look for gluten-free tater tots to ensure the casserole is gluten-free.
Gluten-Free Buns (Crumbled): You could try crumbling GF buns over the casserole for more “Big Mac” flavor without worrying about gluten. Gluten free alternatives are everywhere these days!
Check Labels: Always check the labels of all ingredients to ensure they are gluten-free.

Vegetarian Twists with Plant-Based Meat

Plant-Based Ground Beef: Substitute the ground beef with your favorite plant-based ground meat alternative. I’ve tried it with a few different brands, and it works great!
