Can I use ground beef instead of deli roast beef?

Absolutely! Brown about 1.5 pounds of ground beef with some onions and drain well before using it in place of the deli roast beef. You might want to add a little beef bouillon for extra flavor since deli roast beef typically has more seasoning.

My family doesn't like crispy fried onions. Can I leave them out?

Yes, you can omit the crispy fried onions without ruining the casserole. Consider adding about 1/4 cup of finely diced fresh onion to the beef mixture or substituting with 1/2 cup of sautéed onions for flavor.

Can I make this casserole gluten-free?

Most tater tots are naturally gluten-free, but always check the packaging. The main concern would be the cheddar soup and crispy fried onions, which typically contain gluten. Look for gluten-free versions of these products, or make your own cheese sauce with gluten-free thickeners.

How can I make this casserole a bit healthier?

While this is definitely a comfort food indulgence, you can make it a bit healthier by using reduced-fat cheese, adding vegetables to the beef mixture (like finely chopped spinach or grated carrots), and serving smaller portions alongside a large salad or vegetable side dish.

How to Make Roast Beef and Cheddar Tater Tot Casserole

Step 1: Prepare the Base Mixture

Preheat your oven to 400°F. In a large mixing bowl, combine the chopped roast beef, cheddar soup, ketchup, salt, pepper, Worcestershire sauce, onion powder, and garlic powder. Stir everything together until well combined and evenly coated.

Step 2: Add Texture and Cheese

Add the crispy fried onions and 1 cup of shredded cheddar cheese to the roast beef mixture. Stir well to incorporate these ingredients throughout the mixture. The crispy onions will soften slightly when baked but will add incredible flavor.

Step 3: Assemble the Casserole

Spray a 9×13 inch baking dish thoroughly with cooking spray to prevent sticking. Pour the roast beef mixture into the prepared dish and spread it out in an even layer. This creates the flavorful base of your casserole.

Step 4: Add the Tater Tot Layer

Arrange the frozen tater tots in a single layer on top of the roast beef mixture. Try to cover the entire surface for the best presentation and texture contrast. No need to thaw the tots beforehand – they’ll cook perfectly from frozen.

Step 5: Bake and Add Cheese

Place the casserole in the preheated oven and bake for 35 minutes, until the tater tots are becoming golden and crispy. Remove from the oven and sprinkle the remaining cup of cheddar cheese evenly over the tater tots. Return to the oven for 5-10 more minutes until the cheese is completely melted and starting to brown at the edges.

Step 6: Rest and Serve

Once done, remove the casserole from the oven and let it rest for about 5 minutes. This brief resting period allows the casserole to set up slightly, making it easier to serve and ensuring you don’t burn your mouth on that first delicious bite!

Pro Tips for Making the Recipe

Quality Matters: Choose a good quality deli roast beef – it really makes a difference in the final flavor of the dish.
Even Layer of Tots: Take a moment to arrange your tater tots in a neat single layer rather than just dumping them on. This ensures even cooking and maximum crispiness.
Don’t Rush the Cheese Melt: Those final minutes when the cheese is melting on top are crucial for developing that perfect golden-brown cheese crust.
Season to Taste: Don’t be afraid to adjust the seasonings to suit your family’s preferences. A pinch more garlic powder or an extra dash of Worcestershire sauce can customize the flavor to your liking.
Let It Rest: Those few minutes of resting time at the end make serving much easier and allow the flavors to settle together.

How to Serve

This hearty casserole makes a complete meal on its own, but here are some serving suggestions to round out your dinner:

Side Dishes:

Pair with a crisp green salad dressed with a light vinaigrette to balance the richness of the casserole. Steamed broccoli or roasted vegetables also make excellent nutritious sides.

Toppings:

Set out small bowls of sour cream, sliced green onions, or even pickled jalapeños for people to add to their portions as desired.

Bread:

A basket of warm, crusty bread or soft dinner rolls is perfect for soaking up any extra cheesy sauce.

Make Ahead and Storage

Make Ahead

You can assemble this casserole up to 24 hours in advance. Prepare everything through Step 4, cover with plastic wrap, and refrigerate. When ready to bake, add about 5-10 minutes to the baking time since you’re starting with a cold casserole.

Storing Leftovers

Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. The tater tots won’t stay as crispy, but the flavor actually improves as the ingredients meld together.

Freezing

This casserole freezes beautifully! You can freeze it either before or after baking:

Before baking: Assemble up to Step 4, cover tightly with foil and plastic wrap, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking.
After baking: Cool completely, portion into airtight containers, and freeze for up to 2 months.

Reheating

For best results, reheat individual portions in the microwave for 2-3 minutes or until heated through. To restore some crispiness to the tater tots, reheat in a 350°F oven for about 15-20 minutes.
