Cooking Steps
Preheat oven to 400 F degrees.
In preheated large frying pan or skillet, add the ground beef and break it up with a spatula. Cook on high heat for 3 minutes until it starts to brown. Then add the diced onions, garlic, salt, pepper and stir to combine. Cook for another 5 minutes. Transfer the beef and the onions to the casserole dish with the potatoes.
To the same pan used for the beef, turn the heat to Medium-LOW. Add the butter and stir to melt. Add Flour and whisk to combine with the butter. Cook stirring constantly for about 1 minute, then slowly whisk in the broth and then milk until the roux is completely and smoothly mixed into the liquids. Turn the heat to Medium and continue to stir and cook until it comes to a light simmer and thickens. Turn off the heat.
Whisk in the sour cream, oregano, salt, and pepper to the thickened sauce and then pour the sauce over the potatoes and beef. Add the shredded cheese and then mix to combine everything together.
Bake in the oven center rack for 40 minutes covered with aluminum foil. Remove the cover and bake for another 10 minutes until the potatoes are fork tender. LET REST for 10 minutes.
To serve, scoop on plates. OPTIONAL: Top with a dollop of the Sriracha Mayo and diced pickles. ENJOY!
Can I use ground chicken or turkey in this Hamburger Casserole? Yes, you can use any ground protein that you prefer. Just be sure to add enough oil to the pan for chicken and turkey so that it doesn’t stick, as it has less fat than beef. You will also want to taste for seasoning. Since beef tends to have more natural flavor, you may want a touch more salt, oregano, or pepper. Otherwise, the cooking steps will be the same.
What kind of potatoes should I use in Hamburger Potato Casserole? Yukon Gold are my preferred potato for this recipe. The skins are so thin and delicate that you do not even need to peel them, which is a huge time saver! They also hold shape without turning to mush. You can use russet potatoes, but the skin is tough, so you may want to peel it before dicing and adding it to the recipe.
Can this Hamburger Casserole be cooked in a Slow cooker or Crockpot? Yes, simply follow the instructions as is, up until Cooking step #5. In Cooking Step 5, instead of putting everything in a casserole dish, add to the slow cooker insert. Mix and then set cooking to 6-8 hours, depending on your schedule.
