This Hamburger Hashbrown Casserole is that cozy, crowd-pleasing meal you reach for when you need something easy and filling. With tender potatoes, seasoned beef, and a creamy cheese finish, it’s one of those dishes I make ahead for busy weeks or family gatherings. It is perfect as a main or hearty side and always gets rave reviews when set on the table.
I first made this on a cold night when I wanted something both comforting and convenient. It has since become my go-to for potlucks and get-togethers because there are rarely leftovers to bring home.
Ingredients
- Ground Beef: Look for eighty percent lean beef for the best flavor and to keep things moist
- Yellow Onion: Adds a subtle sweetness and depth chop it finely for even cooking
- French Onion Dip: Choose sour cream based dip from the refrigerated dairy section for creaminess and flavor
- Hash Browns: Either frozen or refrigerated will work but make sure to thaw completely before using
- Colby Cheese: Adds that great melt and mild sharpness try freshly grated for best results or use cheddar if needed
- Cream of Mushroom Soup: Creamy base pulls everything together or sub in cream of chicken soup for a different twist
- Onion Powder: Rounds out the savoriness and boosts onion flavor
- Garlic Powder: Delivers a mellow garlic background
- Black Pepper: Adds mild heat and balances out all the richness
Step-by-Step Instructions
- Brown the Beef and Onion:
- Cook ground beef and diced onion together in a large skillet over medium heat. Stir frequently and cook for at least seven to ten minutes until all pink is gone and onions are softened. Drain off excess fat to keep your casserole from getting greasy. Sprinkle with onion powder, garlic powder, and black pepper after draining to evenly distribute seasoning.
- Combine and Mix:
- In a large nine by thirteen baking dish add thawed hashbrowns cooked beef mixture cream of mushroom soup and French onion dip. Add one cup of shredded Colby cheese. Stir everything together thoroughly so each bite gets a little bit of everything.
- Top with Cheese and Bake:
- Sprinkle remaining cheese over the top of your casserole to guarantee a bubbly top. Place dish in a preheated three hundred fifty degree oven. Bake for forty five to fifty minutes until the surface is golden and cheese is fully melted.
- Cool and Serve:
- Let the casserole rest for five to ten minutes after removing from the oven. This lets the layers firm up so serving clean slices is much easier.

My favorite part about this dish is how the sour cream based onion dip makes everything extra creamy and flavorful. I remember my kids would always ask for seconds on cold nights and the cheesy golden layer on top always disappeared first.
Storage Tips
This casserole keeps well in the fridge for up to four days. Make sure it’s in an airtight container to avoid absorbing fridge odors or drying out. To reheat simply microwave single servings or cover the dish with foil and bake at three hundred fifty degrees until hot throughout.
Ingredient Substitutions
If you do not have cream of mushroom soup cream of chicken works nicely. Cheddar can stand in for Colby and you can swap in seasoned ground turkey for beef. Homemade French onion dip with sour cream and chopped chives is a tasty option.
Serving Suggestions
Serve this as the main dish with a side of green salad for freshness or steamed broccoli for a veggie boost. If you bring this to brunch scoop out generous portions and top with a sprinkle of sliced green onions or a dash of hot sauce.
