Instructions
- Brown the Beef:
- Cook the ground beef with diced onion and minced garlic in a heavy skillet over medium heat. Stir frequently and cook for about 6 to 8 minutes until the beef is browned and crumbled the onions are translucent and the garlic is fragrant. Drain excess grease for a lighter dish.
- Build Flavor:
- Add the tomato paste to the skillet and stir it into the meat mixture. Cook for about 2 or 3 minutes so the tomato paste darkens slightly and loses its raw edge. Mix in the garlic herb seasoning Worcestershire sauce beef bouillon and water. Lower the heat and let everything simmer for a few minutes to meld the flavors.
- Prep the Potatoes:
- Peel and chop your potatoes into bite-sized pieces. Use the microwave to partially cook them for about 8 minutes or parboil them on the stove for about 5 minutes just until slightly tender. Toss them with olive oil and the onion soup mix right in your baking dish spreading them out evenly.
- Layer and Assemble:
- Spoon the seasoned beef mixture evenly over the potatoes. Take a moment to gently level everything in the dish so every bite will be packed with meat and potato.
- Whisk and Pour:
- Combine the cream of mushroom soup with milk and black pepper until smooth. Pour this mixture evenly over the casserole allowing it to seep through the layers for maximum creaminess.
- Bake with Care:
- Cover your baking dish with foil and bake at 375 degrees for 35 minutes. This stage cooks everything through and melds the flavors together.
- Finish with Cheese and Crunch:
- Remove the foil and top the casserole with generous handfuls of grated cheese and crispy fried onions. Bake uncovered for another 7 to 10 minutes until the cheese is melted and bubbly and the onions are deeply golden. Let the casserole rest for 5 minutes before serving so it is easier to scoop.
The first time I scattered crispy fried onions on top my youngest declared it tasted like her favorite snack and now she sneaks extras when I am not looking.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to four days. The casserole reheats well in the oven at 350 degrees until warmed through. If you want to keep the onions crisp add a small sprinkle of fresh fried onions after reheating.
Ingredient Substitutions
Swap ground beef for ground turkey or chicken if you prefer leaner meat. You can use sweet potatoes instead of regular potatoes for a touch of sweetness. Any cream soup works so try cream of celery or cream of chicken for a different twist. Sharp Cheddar or Swiss cheese work beautifully in place of Colby Jack.
Serving Suggestions
Serve with a crisp green salad or simple roasted veggie like broccoli. A slice of buttered sourdough bread or garlic toast turns this into a feast. For special occasions sprinkle fresh chives or parsley on top for a burst of color.
