Smoked Gouda Ranch Mushroom Scalloped Potatoes Tips, FAQ & printable recipe

Tips for success

For the best texture, slice the potatoes as uniformly as possible. A mandoline makes this easy and ensures even cooking. If you prefer a thicker sauce, let the dish rest longer before serving, or use one less can of soup.

To make the top extra golden, you can place the slow cooker insert under the broiler for a few minutes, but make sure the insert is broiler-safe. For a spicier kick, add a pinch of cayenne or a few dashes of hot sauce to the soup mixture.

This dish is incredibly versatile. You can add a layer of sautéed mushrooms or onions for extra depth, or crumble cooked bacon over the top before serving. If you want a lighter version, use reduced-fat cream of mushroom soup and part-skim cheeses, though the texture will be less rich.

The recipe is also forgiving: if you do not have ranch seasoning, a mix of dried dill, garlic powder, and onion powder can substitute. Just be careful with the salt.

Variations

• Add Bacon: For a smoky, savory twist, cook 6 slices of bacon until crisp, crumble, and sprinkle over the top before serving. The bacon adds crunch and a salty punch that complements the creamy potatoes. This is a popular addition for game-day gatherings.
• Vegetable Boost: Layer a cup of sautéed mushrooms, onions, or spinach between the potato slices. Sauté them first to remove excess moisture, then add them to the crock. This adds extra flavor and makes the dish more substantial, turning it into a main course.
• Spicy Ranch: Add 1/2 teaspoon of cayenne pepper or a few dashes of hot sauce to the soup mixture for a spicy kick. You can also use a spicy ranch seasoning mix if available. The heat balances the creaminess of the cheese and soup.
• Herb Garden: Stir in 2 tablespoons of chopped fresh thyme, rosemary, or chives with the ranch seasoning. Fresh herbs brighten the dish and add a garden-fresh aroma. You can also sprinkle some over the top before serving for a pretty finish.

Storage and make-ahead

Fridge

Store in an airtight container in the refrigerator for up to 4 days. Reheat gently, adding a splash of milk or broth if needed to restore creaminess.

Freezer

Freeze for up to 2 months in a freezer-safe container. Thaw overnight in the refrigerator before reheating. The texture of the potatoes may soften.

Reheat

Reheat in the microwave in 1-minute intervals, stirring between, or in a 350°F oven for 15-20 minutes until hot and bubbly.

Store leftover scalloped potatoes in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or in a 350°F oven until warmed through. The sauce may thicken upon standing; stir in a splash of milk or broth when reheating to loosen it.

Leftovers can also be frozen for up to 2 months, though the texture of the potatoes may change slightly after thawing. Thaw overnight in the refrigerator before reheating.

This dish can be assembled a day ahead. Layer the potatoes, soup, ranch seasoning, and cheeses in the slow cooker insert, cover, and refrigerate overnight. The next day, place the insert in the slow cooker and cook on low for 4 to 5 hours, adding about 30 minutes to the cooking time since the ingredients start cold. This makes it perfect for busy holidays or potlucks. Do not stir before cooking; the layers will meld as they heat.

Serving ideas

Serve these scalloped potatoes as a side dish alongside roasted chicken, grilled steak, or pork chops. They also shine on a holiday table next to turkey or ham. The creamy texture pairs well with crisp green vegetables like green beans or a simple salad. For a hearty vegetarian main, serve them with a side of crusty bread and a green salad. The dish is rich, so portion control is easy — a little goes a long way.

Garnish with a sprinkle of fresh chopped parsley or chives just before serving to add a pop of color and freshness. You can also add a few grinds of black pepper. The potatoes are best served hot, straight from the slow cooker.

If you are serving a crowd, keep the slow cooker on the warm setting so everyone can help themselves. The leftovers are just as delicious cold, straight from the fridge, though they are usually gobbled up too quickly for that.

Smoked Gouda Ranch Mushroom Scalloped Potatoes

Prep 15 minCook 4 hTotal 4 h 15 minServes 8

Ingredients

• 3 lb Yukon Gold potatoes, thinly sliced
• 1 can (10.5 oz) condensed cream of mushroom soup
• 1 oz dry buttermilk ranch seasoning mix
• 2 cups shredded smoked gouda
• 1/2 cup freshly grated Parmigiano-Reggiano

Instructions

1. Thinly slice the Yukon Gold potatoes using a mandoline or a sharp knife, aiming for even 1/8-inch rounds. Place the slices in overlapping layers directly in the slow cooker insert, covering the bottom and building up evenly. The layers should be uniform so the potatoes cook at the same rate.
2. Spoon the condensed cream of mushroom soup over the potato layers. Sprinkle the dry buttermilk ranch seasoning mix evenly over the top. Use a spatula or spoon to gently spread the soup and seasoning so they coat the surface of the potatoes as much as possible. Do not stir deeply; the goal is to let the layers remain intact.
3. Sprinkle the shredded smoked gouda evenly over the soup and ranch mixture. Follow with the freshly grated Parmigiano-Reggiano, covering the surface completely. The cheese layer will melt and form a golden, bubbly crust as the potatoes cook.
4. Place the lid on the slow cooker and set it to low heat. Cook for 4 to 5 hours, until the potatoes are fork-tender and the sauce is bubbling around the edges. Avoid lifting the lid during the first 3 hours to keep the heat steady. The cheese will melt into a creamy sauce as the potatoes soften.
5. After 4 hours, check the potatoes by inserting a fork into the center of the casserole. The fork should slide through with little resistance. If the potatoes are still firm, continue cooking in 30-minute increments, checking each time. The sauce should be thickened and creamy, not watery.
6. If the potatoes are tender but the top is not as browned as desired, turn the slow cooker to high for the last 15 to 20 minutes. Watch closely to prevent burning. This step is optional and only for achieving a slightly crisper cheese top. The dish is already fully cooked at this point.
7. Turn off the slow cooker and let the casserole rest, uncovered, for 10 minutes. This allows the sauce to thicken slightly and the potatoes to set, making them easier to serve. The resting time also helps the flavors meld together. Do not skip this step, as the dish will be very hot straight from the cooker.
8. Using a large serving spoon, scoop the scalloped potatoes onto a warm platter or individual plates. Make sure to include some of the creamy sauce and melted cheese with each portion. Serve immediately while hot and bubbly. The potatoes should be velvety and fork-tender.
