This cheesy potato casserole has become my go to comfort food dish, and honestly, it's one of the easiest weeknight dinners I make. The whole thing comes together in about an hour, and most of that is just oven time while you relax. I love that frozen hash browns do all the hard work for you, saving precious prep time. Plus, the garlic and serrano peppers add wonderful flavor and provide natural anti inflammatory benefits that make this feel a bit more wholesome than a typical casserole. Topped with melty cheddar cheese and baked until golden, it's creamy, satisfying, and always a crowd pleaser that won't break the bank.

In a medium pot, melt 1/4 cup butter over medium heat. Add diced onions and cook for 3 to 4 minutes until onions turn translucent but not browned. Then add minced garlic and cook for 30 seconds. Stir in flour and continue to cook for a minute or two until the flour turns a tan color. Slowly whisk in stock and bring sauce to a slight simmer. The sauce will thicken as it heats. Once the sauce is thick like gravy, stir in the cheddar cheese and season with salt and pepper. Remove from heat.

Place the casserole in the center rack of your oven and bake for 45 minutes at 400°F. Then turn on the broiler and broil for 5 minutes on high to crisp up the top of the casserole. If your casserole dish is not broiler-safe, then turn the oven up to 500°F and bake for 3 more minutes.
