It’s a dish that practically begs to be shared, bringing smiles and satisfied sighs around the breakfast table. People adore this casserole because it’s the perfect trifecta of textures and tastes: the satisfying chew of potatoes, the salty crunch of bacon, and the gooey embrace of cheese, all brought together by flavorful ground beef. What truly makes this cheesy beef bacon potato breakfast casserole special is its incredible versatility and the pure, unadulterated joy it brings. It’s robust enough to be a weekend indulgence yet surprisingly simple to assemble, making it an achievable luxury any day of the week.

Cheesy Beef Bacon Potato Breakfast Casserole

Ingredients:

  • 3 large potatoes (peeled and cubed)
  • 1-2 tbsp olive oil
  • 2 tsp salt (divided)
  • 250 g (+-9oz) streaky bacon (chopped)
  • 1 onion (finely chopped)
  • 2 garlic cloves (crushed)
  • 2 cups grated cheddar cheese (divided)
  • 5 eggs
  • ½ cup milk
  • ¾ cup heavy/whipping cream
  • 1 tsp pepper

Prep Work & Initial Cooking

First things first, let’s get our potatoes ready for their starring role in this Cheesy beef bacon potato breakfast casserole. Take your 3 large potatoes and peel them. Once peeled, cut them into bite-sized cubes, roughly ½ inch to ¾ inch. Don’t worry about them being perfectly uniform; a little variation is charming. Now, toss these potato cubes into a pot and cover them with cold water. Add 1 teaspoon of the salt to the water. Bring the water to a boil over medium-high heat and cook the potatoes until they are just fork-tender. This usually takes about 10-15 minutes. You want them tender but not mushy, as they will continue to cook in the oven. While the potatoes are boiling, get a large skillet heating over medium heat. Add your chopped 250g (+-9oz) streaky bacon to the skillet. Cook the bacon, stirring occasionally, until it’s nice and crispy. This is crucial for that wonderful texture in our casserole. Once crispy, use a slotted spoon to transfer the bacon to a plate lined with paper towels to drain off any excess grease. Leave about 1-2 tablespoons of the rendered bacon fat in the skillet; discard the rest.

Building Flavor Layers

Now, into that same skillet with the reserved bacon fat, add your finely chopped onion. Sauté the onion over medium heat until it’s softened and translucent, which should take around 5-7 minutes. You’re aiming for a gentle sweetness to develop. Next, add your 2 crushed garlic cloves to the skillet and cook for another minute until fragrant. Be careful not to burn the garlic, as it can turn bitter. Remove the skillet from the heat and set aside. Once the boiled potatoes are fork-tender, drain them thoroughly and return them to the empty pot or a large bowl. Drizzle the 1-2 tbsp of olive oil over the drained potatoes. Add the remaining 1 teaspoon of salt and the 1 teaspoon of pepper. Gently toss the potatoes to coat them evenly with the oil, salt, and pepper. We’re seasoning them now to ensure every bite is flavorful.

Assembling the Casserole

Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with butter or cooking spray. This step prevents our delicious Cheesy beef bacon potato breakfast casserole from sticking. Now, it’s time to assemble! Spread the seasoned potato cubes evenly across the bottom of the prepared baking dish. Next, scatter the crispy cooked bacon pieces and the sautéed onion and garlic mixture over the potatoes. Make sure to distribute them evenly so every serving gets a good mix of everything. Now, let’s sprinkle about 1 ½ cups of the 2 cups of grated cheddar cheese over the bacon and onion layer. Reserve the remaining ½ cup of cheese for the topping. This cheesy layer will melt into the potatoes and bacon, creating a wonderfully rich base.

The Custard Mixture

In a separate medium bowl, whisk together the 5 eggs until they are well combined. Add the ½ cup of milk and the ¾ cup of heavy/whipping cream to the eggs. Continue whisking until everything is thoroughly incorporated and smooth. This creamy custard mixture is what will bind all the ingredients together and create that delightful, tender texture in your Cheesy beef bacon potato breakfast casserole. Season this mixture with a pinch more salt and pepper if you like, though the bacon and cheese already provide plenty of salinity. Pour this egg and cream mixture evenly over the ingredients in the baking dish. Try to pour it in stages, allowing it to seep down into all the nooks and crannies between the potatoes, bacon, and onions. This ensures an even cook and prevents dry spots.

Baking to Golden Perfection

Now for the final touch before baking. Sprinkle the reserved ½ cup of grated cheddar cheese evenly over the top of the casserole. This will create a beautiful golden-brown, bubbly crust. Cover the baking dish loosely with aluminum foil. This helps to ensure the casserole cooks through evenly without the top burning too quickly. Place the covered casserole dish in the preheated oven. Bake for 30 minutes. After 30 minutes, carefully remove the aluminum foil. Continue to bake for another 20-25 minutes, or until the casserole is set in the center, the potatoes are tender when pierced with a fork, and the cheese on top is melted, golden, and slightly bubbly. The aroma filling your kitchen at this point will be simply irresistible! Let the Cheesy beef bacon potato breakfast casserole rest for about 5-10 minutes before serving. This resting period allows the casserole to set up properly, making it easier to slice and serve. Enjoy this hearty and satisfying breakfast!

Conclusion:

And there you have it! Your incredible Cheesy beef bacon potato breakfast casserole is ready to be devoured. This hearty and satisfying dish is more than just a meal; it’s a celebration of comfort food, perfect for any occasion that calls for something special. The delightful combination of crispy bacon, savory beef, fluffy potatoes, and melted cheese creates a symphony of flavors and textures that will have everyone asking for seconds. It’s a fantastic way to start your day or even as a comforting brunch or dinner option.

For serving suggestions, I love to pair this Cheesy beef bacon potato breakfast casserole with a side of fresh fruit, a dollop of sour cream, or a sprinkle of chives for an extra pop of freshness. If you’re feeling adventurous, consider adding some sautéed bell peppers or onions to the mix for a different flavor profile. This recipe is also incredibly versatile. Don’t have bacon? Try using pancetta or even skip it altogether if you prefer. You can also swap out the cheese for your favorites – Gruyere or sharp cheddar are wonderful alternatives. I truly hope you enjoy making and sharing this delicious casserole. Happy cooking!

Frequently Asked Questions:

Can I make this casserole ahead of time?

Absolutely! You can assemble the Cheesy beef bacon potato breakfast casserole the night before. Cover it tightly with plastic wrap and refrigerate. When you’re ready to bake, let it sit at room temperature for about 20-30 minutes before placing it in the oven. You might need to add a few extra minutes to the baking time.

What kind of potatoes work best?

For the best results in this Cheesy beef bacon potato breakfast casserole, I recommend using starchy potatoes like Russet or Yukon Gold. They tend to become wonderfully fluffy when cooked. Simply dice them into small, uniform pieces to ensure they cook evenly throughout the casserole.
