What Ingredients You Will Need

This cozy cheesy potato casserole recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and substitutions are easy if you have dietary preferences.

• Potatoes: 3 pounds (about 1.4 kg) Yukon Gold potatoes, peeled and thinly sliced (they hold their shape beautifully)
• Cheese Blend: 2 cups (200 g) sharp cheddar cheese, shredded (I recommend Cabot for best melt and flavor)
• 1 cup (100 g) mozzarella cheese, shredded (adds that gooey stretch)
• Butter: 4 tablespoons (60 g) unsalted butter, melted (adds richness and helps the crust crisp up)
• Milk: 1 ½ cups (360 ml) whole milk (feel free to use 2% or dairy-free milk like oat or almond)
• Sour Cream: ½ cup (120 g) sour cream (for tang and creaminess)
• Onion: 1 small yellow onion, finely chopped (sweat it first for sweetness)
• Garlic: 2 cloves, minced (just enough to lift the flavor)
• Flour: 2 tablespoons (16 g) all-purpose flour (helps thicken the sauce)
• Breadcrumb Topping: 1 cup (100 g) panko breadcrumbs (for that perfect golden crunch)
• Seasonings: 1 teaspoon salt, ½ teaspoon freshly ground black pepper, ½ teaspoon smoked paprika (adds subtle warmth)
• Fresh Herbs (optional): 2 tablespoons chopped fresh parsley or chives (for a bright finish)

If you want a gluten-free option, swap the all-purpose flour and panko breadcrumbs for almond flour and gluten-free breadcrumbs. For a dairy-free twist, use vegan cheese and coconut or cashew-based sour cream substitutes.

Equipment Needed

• Baking Dish: A 9×13-inch (23×33 cm) casserole dish works perfectly to layer everything evenly.
• Mixing Bowls: For combining ingredients and prepping the topping.
• Sharp Knife or Mandoline: Thinly slicing potatoes is key—if you have a mandoline, it speeds things up and keeps slices even.
• Skillet: For sautéing onions and garlic before adding to the sauce.
• Measuring Cups and Spoons: Precision really helps with the sauce consistency.
• Whisk: To mix the sauce smoothly without lumps.
• Aluminum Foil: To cover the casserole during baking to prevent over-browning before the final crisp.

If you don’t have a mandoline, no worries—just slice the potatoes as thin as you can with a sharp knife. A cast iron skillet works wonders for the onion sauté, but a non-stick pan does just fine. I keep a silicone spatula handy for scraping every bit of cheesy goodness out of the bowl.

Preparation Method

1. Preheat the oven: to 375°F (190°C). Grease your 9×13-inch (23×33 cm) casserole dish with butter or non-stick spray. This helps everything slide out easily later.
2. Prepare the potatoes: Peel and thinly slice the Yukon Gold potatoes to about 1/8-inch (3 mm) thickness. If you’re using a mandoline, be super careful—those blades are sharp! Rinse the slices briefly in cold water to remove excess starch, then pat dry with a clean kitchen towel.
3. Sauté onions and garlic: In a medium skillet, melt 1 tablespoon (15 g) butter over medium heat. Add the finely chopped onion and cook for 4-5 minutes until translucent and soft. Stir in minced garlic and cook for another 30 seconds until fragrant. Remove from heat.
4. Make the cheese sauce: In a saucepan, melt the remaining 3 tablespoons (45 g) butter over medium heat. Whisk in the flour and cook for about 1-2 minutes to form a roux, stirring constantly to avoid lumps. Slowly whisk in the milk, continuing to stir until the sauce thickens—this usually takes 5-7 minutes. Remove from heat and stir in the sautéed onion and garlic, sour cream, salt, pepper, smoked paprika, and half of the shredded cheddar and mozzarella. Mix well until cheese melts into a creamy sauce.
5. Layer the casserole: Arrange half of the sliced potatoes evenly in the prepared dish. Pour half of the cheese sauce over the potatoes and gently spread to coat. Repeat with the remaining potatoes and sauce. Try not to press down too hard—you want the layers tender but not mashed.
6. Add the breadcrumb topping: In a small bowl, mix panko breadcrumbs with a tablespoon of melted butter. Sprinkle evenly over the top of the casserole for that coveted golden crust.
7. Bake covered: Cover the casserole loosely with foil and bake for 45 minutes. This keeps the potatoes steaming and ensures even cooking.
8. Finish baking uncovered: Remove the foil and bake for another 15-20 minutes until the top is golden brown and crispy. You’ll know it’s done when the cheese sauce bubbles up and the crust crackles to a perfect crunch.
9. Rest before serving: Let the casserole sit for 10 minutes after baking to set up—that way, it slices cleanly and all those wonderful flavors settle in.

If your potatoes aren’t tender after 45 minutes covered, don’t sweat it—oven temperatures vary. Just give it a little more time before uncovering for the crust. Also, if you notice the topping browning too fast, tent foil back on to avoid burning.

Cooking Tips & Techniques

One pro tip I’ve learned is to slice those potatoes evenly thin—this helps them cook uniformly without turning into mush. Honestly, using Yukon Golds (instead of russets) keeps the texture creamy but firm, which is a game changer. When making the cheese sauce, whisk constantly to avoid lumps and cook the roux long enough to remove the raw flour taste. It’s tempting to rush, but patience here pays off big time.

Another heads-up: sautéing the onions and garlic first adds a subtle sweetness that plain raw additions just can’t match. Don’t skip this step even if you’re in a hurry. For the crispy topping, panko breadcrumbs are your best friend — regular breadcrumbs tend to get soggy. Tossing them with melted butter before sprinkling helps them toast evenly and get that golden crunch.

Timing-wise, I usually prep the casserole up to layering the night before, then refrigerate it covered. When ready to bake, just add the topping and go. This makes busy days so much easier. Just remember to add a few extra minutes to the bake time if starting cold from the fridge.

Lastly, resist the urge to stir once it’s in the oven—this is a casserole, not a soup! Let those layers do their thing and transform into cheesy potato heaven.

Variations & Adaptations

This cozy cheesy potato casserole is pretty forgiving and easy to customize based on what you have or your dietary needs. Here are a few variations I’ve tried and loved:

• Vegetable Boost: Add sautéed mushrooms, spinach, or roasted red peppers between potato layers for extra color and nutrition.
• Smoky Bacon Twist: Toss in cooked, crumbled bacon or pancetta for a smoky, savory punch that pairs amazingly with the creamy cheese.
• Herb & Spice Variations: Swap smoked paprika for cayenne or chipotle powder for heat, or add fresh thyme and rosemary for an herbal note.
• Gluten-Free Version: Use almond flour or gluten-free all-purpose flour for the sauce and gluten-free breadcrumbs to keep it crispy.
• Dairy-Free Option: Sub coconut cream for sour cream and vegan cheese shreds for a friendly alternative that still melts nicely.

I once tried swapping half the potatoes with sweet potatoes for a touch of natural sweetness and vibrant color—it was a total hit with the family, and the crust still got that perfect crunch.

Serving & Storage Suggestions

This casserole is best served warm, straight from the oven, with the golden crust crackling under your fork. I like to garnish with freshly chopped parsley or chives to brighten it up just before serving. It pairs wonderfully with a crisp green salad or roasted veggies to balance the richness.

If you’re serving a crowd, this dish holds up well on a buffet table and even tastes great the next day. Store leftovers tightly covered in the refrigerator for up to 3 days. To reheat, cover with foil and warm at 350°F (175°C) for 15-20 minutes until heated through. For a quick fix, microwave individual portions but beware the crust won’t stay as crispy.

Freezing is also an option: freeze the casserole before baking, wrapped tightly, for up to 2 months. Thaw overnight in the fridge and bake as directed, adding extra time if needed. The flavors actually deepen after a day or two in the fridge, making leftovers even better in my humble opinion.

Nutritional Information & Benefits

This cheesy potato casserole offers a comforting source of energy with a decent balance of protein, carbs, and fats. One serving (about 1 cup or 240 g) typically contains approximately:

Nutrient	Amount
Calories	320
Protein	12 grams
Carbohydrates	30 grams
Fat	15 grams

Potatoes provide potassium and vitamin C, while cheese adds calcium and protein. Choosing whole milk and sour cream adds richness but also fat, so feel free to swap for lighter versions if you want a less indulgent dish. For those avoiding gluten or dairy, the substitutions mentioned earlier keep it accessible without losing the essence of cozy comfort.

Make sure to slice potatoes evenly and rinse them to remove excess starch. Cover the casserole while baking to steam properly, then uncover for the crispy topping.

Absolutely! Assemble it the night before, keep it covered in the fridge, and bake when ready. Just add a few extra minutes to the baking time if it’s cold from the fridge.

What’s the best cheese combination for this recipe?

I recommend sharp cheddar for flavor and mozzarella for meltiness. You can also add Monterey Jack or Gruyère if you want a twist.

Is this recipe suitable for vegetarians?

Yes! It’s vegetarian as is, but if you add bacon or pancetta, it won’t be. You can easily keep it meat-free and still delicious.
