Step‑by‑Step Instructions for Cheesy Bacon Potato Breakfast Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 180ºC (350ºF). This is the ideal temperature for cooking the Cheesy Bacon Potato Breakfast Casserole evenly and achieving a beautifully golden, bubbly top. While the oven heats up, you can get your ingredients ready and move on to the next steps.
Step 2: Roast the Potatoes
Cube your large potatoes and toss them with olive oil and a generous pinch of salt. Spread them on a baking sheet in a single layer, ensuring they are not overcrowded. Roast in the preheated oven for about 30 minutes, or until they turn golden and crisp. Stir halfway through to ensure even cooking and browning.
Step 3: Cook the Bacon and Vegetables
In a large skillet, cook the chopped bacon over medium heat until it’s nice and crispy, which should take about 5–7 minutes. Once the bacon is cooked, add the finely chopped onion and continue to cook until softened, about 3-4 minutes. Toss in the crushed garlic for the final 20 seconds to infuse its aroma into the mixture.
Step 4: Combine the Ingredients
In a large casserole dish, combine the roasted potatoes, crispy bacon, and onion-garlic mixture. Stir gently to evenly distribute the ingredients, then sprinkle half of the grated cheddar cheese over the top. This will provide a rich, cheesy flavor throughout your Cheesy Bacon Potato Breakfast Casserole.
Step 5: Whisk the Egg Mixture
In a mixing bowl, whisk together the eggs, milk, heavy cream, remaining salt, and pepper until well combined. This mixture will bind all the layers together, contributing to a delightful texture. Pour it evenly over the potato mixture in the casserole dish, allowing it to seep through the layers.
Step 6: Add More Cheese and Bake
Sprinkle the remaining grated cheddar cheese on top of the casserole, creating a delicious cheesy crust. Place the casserole dish in the oven and bake for 30-40 minutes, or until the casserole is set in the center and the top is golden and bubbling. Keep an eye on it during the last few minutes for that perfect golden finish.
Step 7: Cool and Serve
Once baked, remove the Cheesy Bacon Potato Breakfast Casserole from the oven and let it cool for 5-10 minutes. This cooling time allows the flavors to settle and makes for easier slicing. Serve warm, and enjoy a cozy breakfast that’s full of comforting flavors!

Make Ahead Options
These Cheesy Bacon Potato Breakfast Casseroles are perfect for meal prep enthusiasts! You can prepare the entire casserole up to 24 hours in advance by following the initial steps, then cover it tightly with plastic wrap or aluminum foil and refrigerate. This keeps the flavors fresh and prevents the potatoes from browning. When you’re ready to serve, simply remove it from the fridge and bake it straight from cold at 180ºC (350ºF) for an additional 10-15 minutes to ensure it’s hot throughout. This way, you’ll enjoy a satisfying, homemade breakfast with minimal effort on busy mornings!
