📋 Ground Beef and Potato Casserole (with spinach) Recipe
This Ground Beef and Potato Casserole (with spinach) is a complete meal in one pot. With sliced potatoes, frozen spinach, ground beef/hamburger and Swiss cheese, you get your entire dinner in one dish!
Preheat oven to 350 degrees F/176 degrees C and Grease and 9" X 11" casserole dish
Cook ground beef in skillet with diced onion until browned and cooked through. Drain and set aside.
1 ½ lbs extra lean ground beef, 2 small onions
Slice potatoes into ¼ inch thick rounds.
8 small - medium potatoes
Place sliced potatoes on a plate and cover with saran wrap. Alternatively, you can simply cover it with a microwave safe cover if you don't want to use saran wrap.
Cook in the microwave for 8 minutes. *I do this in 2 batches. but it can be done in 1 batch if the potatoes are sliced a little thinner. If you want to cook them in one batch, you’ll need to cook them for 12 minutes in the microwave.**BE CAREFUL when you take the saran wrap off ( if you use it) as lots of steam is released and it's HOT!
Melt butter in separate bowl in microwave safe bowl.
5 tablespoon unsalted butter, melted
Arrange half of the potatoes in bottom of dish and drizzle with half the butter.
In a separate medium mixing bowl, mix ½ cup grated Swiss cheese, spinach, cottage cheese, garlic, salt and egg. Then add ground beef./onion mixture and Worcestershire sauce. Mix well.
Spread the spinach and ground beef mixture over the first layer of potatoes and butter.
Cover with remaining potatoes, drizzle with remaining 2 ½ tablespoon butter.
Sprinkle with remaining 1 ½ cups Swiss cheese.
Bake 40-50 minutes or until potatoes are soft. Cool for 5 minutes
Garnish
Garnish with chopped chives or green onions. I love to serve this with ketchup!

Notes
*NOTE: The final images and the process images were photographed under different lighting conditions. I also sliced the potatoes by hand in the final photos and used a food processor to slice them for the process photos. Storage:This ground beef and potato casserole recipe can be stored for up to 4 days in an airtight container in the fridge and reheated in the microwave.I do NOT recommend freezing it.Expert Recipe Tips
Use Thin and Even Potato Slices. For the best texture, slice the potatoes evenly at about ¼ inch thick. If using a food processor or mandoline slicer, try ⅛ inch for ultra-thin slices, which may eliminate the need for pre-cooking.
Pre-Cook Potatoes for Even Cooking. Microwaving the potato slices before assembling ensures they cook through in the oven. If skipping this step, increase the baking time by 10-15 minutes and cover with foil for the first half of baking to prevent excessive browning.
Drain Spinach Well. Squeeze out as much liquid as possible from the defrosted spinach. Excess moisture can make the casserole watery. A clean kitchen towel works best for wringing out spinach.
Enhance Flavor with Seasoning Layers. Instead of just mixing the salt and pepper into the meat mixture, try seasoning each layer (potatoes, spinach mixture, and beef) lightly. This helps distribute the flavor more evenly throughout the dish.
Boost Cheesiness with a Mix of Cheeses. While Swiss cheese is delicious, try blending it with sharp cheddar, Monterey Jack, or Gruyère for extra depth of flavor. A sprinkle of Parmesan on top before baking adds a delicious golden crust
Let the Casserole Rest Before Serving. After baking, let the casserole rest for 5-10 minutes before cutting. This helps the layers set and prevents it from falling apart when serving.
Make It a One-Pan Meal. Reduce cleanup, brown the ground beef in an oven-safe skillet, then layer the ingredients directly in the same pan before baking. This also helps retain extra flavor from the beef.
Adjust Baking Time Based on Dish Depth. If using a deeper baking dish, you may need to increase the baking time by 5-10 minutes to ensure the center is fully cooked. A shallower dish will cook faster and provide more crispy edges.
