You know that moment when you’ve had a long day and all you want is something warm, cheesy, and utterly comforting? Not a salad. Not another takeout box. I’m talking about something cozy, hearty, and soul-satisfying—like a hug in food form. Enter: Cheesy Mashed Potato and Beef Casserole.
Think of it as the lovechild of shepherd’s pie and mac and cheese: creamy mashed potatoes, rich and savory beef, all topped with ooey-gooey cheese. And the best part? It’s surprisingly simple to make with ingredients you probably already have in your kitchen.
Why This Casserole Should Be in Your Weekly Rotation
This dish is a total game-changer, and here’s why it’s a weekly favorite in my house:
- Feeds a crowd: From picky kids to teens with bottomless appetites, or that partner who claims they’re “not that hungry”—this casserole wins them all over.
- Make-ahead magic: Prep it in the morning, pop it in the fridge, and bake it later. You can even double the recipe and freeze half for a backup meal—hello, stress-free weeknights!
Ingredients You’ll Need
For the Beef Layer:
- 1 lb (450g) ground beef
- 1 medium onion, finely chopped
- 2 garlic cloves, minced
- 1 cup marinara or tomato sauce
- 1 tbsp tomato paste
- 1 tbsp Worcestershire sauce
- 1 tsp paprika
- Salt and pepper to taste
- 1 tbsp olive oil
For the Mashed Potatoes:
- 4 large potatoes, peeled and cubed
- 1/4 cup butter
- 1/2 cup milk or cream (cream for extra richness)
- Salt and pepper to taste
For the Cheese Layer:
- 2 cups shredded cheddar or mozzarella cheese (cheddar for bold flavor, mozzarella for gooey melt)
- 1/4 cup grated Parmesan (optional, but highly recommended!)
Step-by-Step: How to Make This Comfort Classic
1. Cook the Potatoes
Start with the potatoes—they’ll take the longest. Peel, chop, and boil in salted water for 15–20 minutes, or until fork-tender.
Drain and mash with butter, milk (or cream), and a pinch of salt and pepper. Aim for smooth and creamy—thick, not runny.
Quick tip: Short on time? Use leftover mashed potatoes—just warm them slightly before spreading.
2. Prepare the Flavorful Beef Layer
Heat olive oil in a skillet over medium heat. Sauté onions until soft, then add garlic and cook for another minute. Toss in the ground beef and cook until browned, breaking it apart as you go.
Add tomato sauce, tomato paste, Worcestershire sauce, paprika, salt, and pepper. Simmer for 5 minutes until thickened.
Optional twist: Add mushrooms, peas, or bell peppers for extra veggies.
3. Assemble the Casserole
Grab a 9×13-inch baking dish. Spread the beef layer evenly across the bottom. Layer mashed potatoes on top, smoothing like frosting.
Sprinkle shredded cheese generously and finish with Parmesan if you’re feeling fancy.
4. Bake to Golden Perfection
Preheat oven to 375°F (190°C). Bake uncovered for 20–25 minutes, until cheese is melted and slightly golden. Crispy edges are the goal here.
Let it rest 5–10 minutes before serving so it sets nicely.
Customize It Your Way
This casserole is a canvas—feel free to tweak it:
- Spicy: Add cayenne or use pepper jack cheese.
- Veggie-loaded: Spinach, corn, or bell peppers mix in nicely.
- Low-carb: Try mashed cauliflower (but potatoes are classic comfort, so no judgment if you skip this).
- Extra cheesy: Fold cream cheese into the mashed potatoes for indulgent creaminess.
Serving Suggestions
While this casserole can stand alone, a few sides never hurt:
- Crisp green salad (ranch, please!)
- Garlic bread or dinner rolls
- Roasted green beans or broccoli
- Pickles or coleslaw for a tangy contrast
Storing and Reheating
- Fridge: Store leftovers in an airtight container for 3–4 days. Reheat in the oven at 350°F until warmed, or microwave if you’re in a hurry.
- Freezer: Freeze before or after baking (let cool first). Wrap tightly in foil—lasts up to 2 months. Thaw overnight in the fridge before reheating.
