Ingredients

For this delicious Creamy Ranch Potato Casserole, you’ll need:

• 3 pounds (1.4 kg) russet potatoes, thinly sliced (about ⅛-inch thick)
• 2 cups (473 ml) heavy cream
• 1 cup (240 ml) whole milk
• 2 tablespoons ranch seasoning mix (store-bought or homemade)
• 3 cloves garlic, minced
• 2 cups (8 oz/225g) shredded cheddar cheese
• 1 cup (4 oz/113g) shredded mozzarella cheese
• ½ cup (2 oz/56g) grated Parmesan cheese
• 8 slices bacon, cooked and crumbled (about ½ cup)
• 3 green onions, thinly sliced
• 2 tablespoons fresh chopped parsley
• Salt and pepper to taste

The ranch seasoning is the star ingredient that infuses the entire dish with its signature tangy, herbaceous flavor. For the potatoes, russets work best as they hold their shape while becoming tender and absorbing the creamy sauce. The three-cheese blend provides different textures and flavor notes – sharp cheddar for depth, mozzarella for that irresistible stretch, and Parmesan for a salty finish.

Pro Tips

Potato Preparation: For the best texture in your Creamy Ranch Potato Casserole, slice the potatoes to a uniform thickness (about ⅛-inch). Using a mandoline slicer ensures consistency and even cooking. Don’t rinse the potatoes after slicing – the natural starch helps thicken the cream sauce. If cutting ahead of time, keep sliced potatoes submerged in cold water with a splash of lemon juice to prevent browning, but be sure to thoroughly dry them before assembling.

Layering Technique: Build flavor in every bite by seasoning each layer individually rather than just the top. After placing each layer of potatoes, add a light sprinkle of salt, pepper, and a small amount of cheese before adding the next layer. This creates a well-seasoned casserole throughout rather than just on the surface. Reserve about ⅓ of your cheese mixture for the top to achieve that perfect golden-brown crust.

Baking Perfection: For the ultimate Creamy Ranch Potato Casserole, cover the dish with foil for the first 40 minutes of baking, then remove it for the final 20-30 minutes. This two-stage method ensures the potatoes cook through completely while still allowing the top to become beautifully golden and slightly crispy. Let the casserole rest for 15 minutes before serving – this crucial step allows the sauce to set slightly so your casserole holds together better when served.

Instructions

Step 1: Prep Your Ingredients
Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish. Thinly slice your potatoes to about ⅛-inch thickness, using a mandoline if available for consistency. In a large mixing bowl, combine the heavy cream, milk, ranch seasoning, and minced garlic, whisking until well incorporated. In a separate bowl, toss together the cheddar, mozzarella, and half the Parmesan cheese.

Step 2: Create Your Base Layer
Arrange one-third of your sliced potatoes in the bottom of your prepared baking dish, slightly overlapping them. Season with a pinch of salt and pepper, then pour approximately one-third of your ranch cream mixture over the potatoes. Sprinkle with one-quarter of your cheese mixture and a small amount of the crumbled bacon.

Step 3: Build Your Casserole
Repeat the layering process twice more with the remaining potatoes, ranch mixture, and cheese, reserving about ⅓ of the cheese and some bacon for the final topping. Each layer should be seasoned lightly with salt and pepper to ensure flavor throughout your Creamy Ranch Potato Casserole.

Step 4: Add The Final Touch
Top the casserole with your remaining cheese mixture, the rest of the Parmesan, and the remaining bacon crumbles. This creates that irresistible golden crust everyone will fight over.

Step 5: Bake To Perfection
Cover the baking dish with aluminum foil and bake for 40 minutes. Then remove the foil and continue baking for an additional 25-30 minutes until the top is golden brown and bubbly, and the potatoes are fork-tender. If you want an extra golden top, you can broil for the final 2-3 minutes, watching carefully to prevent burning.

Step 6: Rest And Garnish
Allow your Creamy Ranch Potato Casserole to rest for 15 minutes before serving – this is crucial for the sauce to thicken slightly. Garnish with sliced green onions and fresh parsley just before bringing it to the table for a pop of color and fresh flavor that complements the rich, creamy casserole.

Variations

Loaded Baked Potato Style: Transform your Creamy Ranch Potato Casserole into a loaded baked potato experience by adding extra toppings. Mix in 1 cup of sour cream with the ranch mixture for added tanginess. After baking, top with extra bacon, chopped chives, and a dollop of sour cream for that classic loaded potato flavor. This variation makes an excellent side dish for grilled steaks or barbecued meats.

Southwest Ranch Potato Casserole: Add a spicy kick to your casserole by incorporating 1 can of drained diced green chiles, 1 teaspoon of cumin, and ½ teaspoon of chili powder to the ranch mixture. Replace half the cheddar with pepper jack cheese for added heat. Top with diced avocado, fresh cilantro, and a squeeze of lime after baking for a Tex-Mex inspired twist on the traditional potato ranch bake. This variation pairs wonderfully with grilled chicken or as part of a Mexican-themed dinner.

Lighter Version: For a lighter take on this Creamy Ranch Potato Casserole, substitute the heavy cream with half-and-half or a combination of milk and Greek yogurt. Use reduced-fat cheese and turkey bacon instead of regular bacon. Add extra vegetables like steamed broccoli florets or spinach between layers for added nutrition. This version still delivers great flavor with fewer calories and less fat.

Storage and Serving

Your Creamy Ranch Potato Casserole can be refrigerated in an airtight container for up to 4 days. For best results, let it cool completely before transferring to storage containers. When reheating, cover with foil and warm in a 350°F oven for about 20 minutes, or until heated through. For individual portions, microwave for 1-2 minutes, though the texture will be slightly different than oven reheating.

For freezing, prepare the casserole but don’t bake it. Cover tightly with plastic wrap and aluminum foil, then freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed, adding about 15 extra minutes to the cooking time.

Serve this casserole alongside grilled or roasted meats for a complete meal. It pairs beautifully with herb-roasted chicken, grilled steak, or baked ham. For a satisfying meatless meal, serve larger portions with a fresh green salad dressed with a light vinaigrette to balance the richness of the casserole. For brunch, top individual servings with a fried egg for an indulgent weekend treat that combines the best of breakfast and lunch flavors.

FAQs

Can I make this Creamy Ranch Potato Casserole ahead of time?
Yes, you can assemble the casserole up to 24 hours in advance. Keep it covered in the refrigerator until ready to bake. You may need to add 10-15 minutes to the baking time if cooking directly from the refrigerator.

What type of potatoes work best for this casserole?
Russet potatoes are ideal due to their starch content and ability to hold shape while becoming tender. Yukon Gold potatoes also work well and provide a slightly buttery flavor. Avoid waxy potatoes like red potatoes as they don’t absorb the creamy sauce as effectively.

Can I use homemade ranch seasoning instead of store-bought?
Absolutely! A basic homemade mix includes dried dill, garlic powder, onion powder, dried parsley, salt, pepper, and a touch of buttermilk powder. Using homemade allows you to control the sodium and avoid preservatives.

Why is my casserole watery?
This typically happens if the potatoes weren’t dried properly after washing or if the casserole wasn’t baked long enough. Ensure potatoes are patted dry and that the casserole reaches a bubbly, golden state before removing from the oven.

Can this recipe be made vegetarian?
Yes, simply omit the bacon or substitute with vegetarian bacon bits. The cheese and ranch seasoning provide plenty of flavor on their own. Check your ranch seasoning ingredients as some commercial mixes contain animal products.
