Cheesy Bacon Scalloped Potatoes: A Comfort Food Classic

My grandmother, bless her heart, was the queen of comforting casseroles. I can still picture her standing in her sun-drenched kitchen, humming softly as she layered thinly sliced potatoes into a buttered dish. While her version was always delicious, it wasn’t until I added a touch of crispy bacon and creamy Colby cheese that I truly understood the magic of scalloped potatoes. The smoky saltiness of the bacon, the sharp tang of the cheese, and the tender, earthy potatoes all meld together in a symphony of flavor that warms you from the inside out. This Cheesy Bacon Scalloped Potatoes recipe is my tribute to her, with a little added flair.

Recipe Overview

Prep Time: 20 minutes
Cook Time: 1 hour 15 minutes
Total Time: 1 hour 35 minutes
Servings: 6-8
Yield: 1 casserole
Dietary Type: Not Gluten-Free

Ingredients

5-8 large baking potatoes (I use Idaho Potatoes)
1 tablespoon butter
½ medium sweet onion, diced
1 teaspoon minced garlic
2 tablespoons butter
3 tablespoons flour
2 ½ cups milk
¼ – ½ cup Colby cheese, crumbled (not shredded)
⅛ – ¼ cup crumbled bacon (I use the “Real Bacon Crumbles” you use for salad toppings to save time)
Salt and pepper, to taste
Parmesan cheese, sprinkled on top (optional)
¼ cup breadcrumbs (optional)
2 tablespoons melted butter (optional, for breadcrumb topping)

Equipment Needed

Large bowl
Small saucepan
2 qt Casserole dish
Knife or mandoline
Whisk

Instructions

Peel the potatoes and slice them thinly. A mandoline makes quick work of this, but a sharp knife works just fine. Place the sliced potatoes in a bowl of cold water to prevent them from browning.
In a skillet, sauté the diced onion with 1 tablespoon of butter until golden.
Add the minced garlic and continue to sauté until the garlic is lightly colored and fragrant, about 1 minute. Be careful not to burn the garlic. Remove the skillet from the heat and set aside.
In a small saucepan, melt 2 tablespoons of butter over medium heat.
Add 3 tablespoons of flour to the melted butter. Stir constantly with a whisk until the mixture begins to bubble. This creates a roux, which will thicken the sauce.
Slowly add 2 ½ cups of milk, whisking constantly to prevent lumps from forming. Continue stirring and bring the sauce to a boil.
Once boiling, reduce the heat to low and simmer for 2-4 minutes, stirring occasionally, until the sauce is thickened to your liking. It should be able to coat the back of a spoon.
Drain the potatoes thoroughly.
Spray or grease a 2-quart casserole dish.
Add the drained potatoes to the casserole dish.
Add the sautéed onions and garlic to the potatoes.
Pour the creamy sauce evenly over the potatoes and onion/garlic mixture.
Season with salt and pepper to taste. It’s best to taste the sauce and adjust seasoning as needed.
Sprinkle the crumbled bacon pieces and crumbled Colby cheese over the top.
Lightly hand mix all ingredients throughout the dish, ensuring the sauce coats the potatoes and the bacon and cheese are evenly distributed.
(Optional) For a crispy topping, sprinkle Parmesan cheese on top and/or combine ¼ cup breadcrumbs with 2 tablespoons of melted butter. Sprinkle this mixture evenly over the top of the casserole.
Bake in a preheated oven at 400°F (200°C) for 1 to 1 ½ hours uncovered, or until the top is golden brown and the potatoes are tender.
If you added the breadcrumb mixture, cover the casserole dish with foil for the first 45-60 minutes of the cooking time to prevent the breadcrumbs from burning due to the high temperature and long cooking time.
Check for doneness by inserting a fork into the center of the casserole. The potatoes should be easily pierced and offer very little resistance.
Remove from oven and let stand for 10 minutes before serving.

Expert Tips & Tricks

For a smoother sauce, use whole milk or half-and-half instead of lower-fat milk options.
If you want a deeper smoky flavor, try using smoked bacon or add a dash of smoked paprika to the sauce.
To prevent the cheese from burning on top, you can add it during the last 30 minutes of baking time.
Make ahead: Assemble the casserole and store it in the refrigerator for up to 24 hours before baking. Add about 15 minutes to the baking time.
If your sauce is too thick, add a splash of milk until you reach your desired consistency. If it’s too thin, mix a tablespoon of cornstarch with two tablespoons of cold water, then whisk it into the sauce and simmer for a few minutes until thickened.

Serving & Storage Suggestions

Serve the Cheesy Bacon Scalloped Potatoes hot and bubbling straight from the oven. It’s a fantastic side dish for roasted chicken, ham, or even a hearty steak. Garnish with fresh parsley or chives for a pop of color.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, bake in a preheated oven at 350°F (175°C) until heated through, or microwave in short intervals. For best results, add a splash of milk or cream before reheating to prevent the potatoes from drying out.

While it can be frozen, the texture of the potatoes may change slightly upon thawing. If freezing, wrap tightly in plastic wrap and then foil. It can be stored in the freezer for up to 2 months. Thaw completely in the refrigerator before reheating.
