What You’ll Need: The Ingredients
Here’s a breakdown of everything you’ll need to create this masterpiece. Don’t worry, I’ve got you covered with tips and substitutions along the way!For the Ground Beef Layer:
- 1 pound ground beef: I prefer lean ground beef (85/15) to minimize grease, but feel free to use what you have on hand.
- 1 medium onion, chopped: Yellow or white onions work great.
- 2 cloves garlic, minced: Fresh garlic is best, but 1 teaspoon of garlic powder can be substituted if you’re in a pinch.
- 1 (15 ounce) can tomato sauce: Adds a rich, savory depth.
- 1 teaspoon Italian seasoning: This blend of herbs is a flavor booster!
- 1/2 teaspoon salt: Adjust to your taste.
- 1/4 teaspoon black pepper: Freshly ground is always best.
- 1 tablespoon olive oil: For sautéing the vegetables.
For the Potato Layer:
- 2 pounds potatoes, peeled and thinly sliced: Russet potatoes are my go-to for this casserole because they bake up fluffy, but Yukon Gold or red potatoes will also work.
- 1/2 cup milk: Whole milk creates the creamiest texture, but any milk will do.
- 1/4 cup butter, melted: Adds richness and flavor.
- 1/2 teaspoon salt: Season those potatoes!
- 1/4 teaspoon black pepper: Adds a little kick.
For the Cheese Topping:
- 2 cups shredded cheddar cheese: Sharp cheddar is my favorite for its bold flavor, but you can use any cheese you like – Monterey Jack, Colby Jack, or even a blend.
Step-by-Step: Building Your Casserole Masterpiece
Alright, let’s get cooking! This is where the magic happens. I’ll walk you through each step, so don’t worry, it’s easier than you think.
Prepping the Ground Beef:
- Sauté the Vegetables: Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook until softened, about 5 minutes. Add the minced garlic and cook for another minute until fragrant.
- Brown the Beef: Add the ground beef to the skillet and cook, breaking it up with a spoon, until browned. Drain off any excess grease. This is a MUST to avoid a greasy casserole!
- Simmer the Sauce: Stir in the tomato sauce, Italian seasoning, salt, and pepper. Bring to a simmer and cook for 10 minutes, stirring occasionally, to allow the flavors to meld.
Assembling the Potato Layer:
- Prepare the Potatoes: In a large bowl, combine the thinly sliced potatoes, milk, melted butter, salt, and pepper. Toss to coat evenly.
Layering and Baking:
- Preheat the Oven: Preheat your oven to 375°F (190°C).
- Layer the Casserole: Grease a 9×13 inch baking dish. Spread the ground beef mixture evenly in the bottom of the dish. Arrange the potato slices over the ground beef, overlapping them slightly. This is important for even cooking!
- Bake: Cover the dish with aluminum foil and bake for 45 minutes.
- Add the Cheese: Remove the foil and sprinkle the shredded cheddar cheese evenly over the potatoes. Bake for another 15-20 minutes, or until the cheese is melted and bubbly and the potatoes are tender.
- Rest: Let the casserole rest for 10 minutes before serving. This allows the cheese to set and the flavors to meld even further.
