In a large skillet over medium-high heat, cook the ground beef until browned, about 5-7 minutes.
Add the diced onions and minced garlic, and cook until the onions are translucent, about 3-4 minutes.
Stir in the tomato sauce, salt, black pepper, oregano, paprika, and cayenne pepper (if using). Reduce the heat to low and simmer for 5-7 minutes, stirring occasionally.
Remove from heat and set aside.
Step 2: Prepare the Mashed Potatoes
In a large pot, boil the cubed potatoes in salted water until tender, about 15-20 minutes.
Drain the potatoes and return them to the pot.
Add the milk, butter, salt, and black pepper. Mash the potatoes until smooth and creamy using a potato masher or electric mixer.
Set the mashed potatoes aside while you assemble the casserole.
Step 3: Assemble the Casserole
Grease a 9×13-inch baking dish.
Spread half of the mashed potatoes evenly across the bottom of the dish.
Spoon the cooked ground beef mixture over the mashed potatoes, spreading it evenly.
Top the ground beef layer with the remaining mashed potatoes, smoothing it out.
Sprinkle the shredded cheddar and mozzarella cheeses evenly over the top of the mashed potatoes.
Step 4: Bake the Casserole
Place the casserole in the preheated oven and bake for 25-30 minutes, or until the cheese is melted and bubbly, and the edges are golden brown.
Remove from the oven and let it rest for 5-10 minutes before serving.
Step 5: Serve
Garnish with fresh parsley for color and freshness.
Serve hot, accompanied by a green salad, roasted vegetables, or a side of bread.
Tips:
For added flavor, you can add a pinch of cumin or smoked paprika to the ground beef mixture.
If you prefer a creamier texture, you can add a dollop of sour cream or heavy cream to the mashed potatoes.
You can also add diced bell peppers or mushrooms to the ground beef mixture for extra texture and flavor.
Enjoy your delicious Cheesy Ground Beef and Potato Casserole! 😊
