• 1 cup shredded Gruyère cheese (or sharp cheddar)

3. Step-by-Step Instructions to Make French Onion Potato Bake

Preparation of Onions and Caramelization

Begin by heating the butter and olive oil in a large skillet over medium heat. Add the sliced onions and a pinch of salt, cooking slowly until they become soft and caramelized — about 20-25 minutes. Stir occasionally to prevent burning. Once caramelized, add the minced garlic and cook for an additional minute, then set aside.

Preparing the Potatoes

Wash and thinly slice the potatoes using a mandoline or sharp knife. Rinse them in cold water to remove excess starch, then pat dry with paper towels. This ensures even layering and prevents sogginess.

Assembling the Cheesy Onion Potato Bake

Preheat your oven to 375°F (190°C). Lightly grease a baking dish. Spread a layer of potato slices at the bottom, then top with caramelized onions. Repeat layers until all ingredients are used, finishing with a layer of potatoes. In a mixing bowl, combine sour cream, milk, salt, pepper, and half of the shredded cheese. Pour this mixture evenly over the layered potatoes and onions. Sprinkle the remaining cheese on top.

Baking to Perfection

Cover the baking dish with foil and bake for 40 minutes. Remove the foil and bake for an additional 15 minutes, until the top is golden and bubbly. Let the dish rest for about 10 minutes before serving, allowing the flavors to settle.

4. Storage Tips for Leftover French Onion Potato Bake

Cool any leftovers to room temperature before transferring to an airtight container. Store in the refrigerator for up to 3 days. To reheat, place in a 350°F (175°C) oven for 15-20 minutes or microwave in short bursts until warmed through. For best results, reheat without covering to maintain a crispy top layer.

5. Serving Suggestions for Your French Onion Potato Bake

This cheesy onion potato bake pairs wonderfully with roasted meats, grilled vegetables, or a fresh green salad. For added flavor, sprinkle with chopped fresh herbs like parsley or thyme before serving. For a complete holiday meal, consider serving with creamy garlic sausage rigatoni or a hearty roast.
