Ingredients You’ll Need for French Onion Potato Bake
- 2 lbs potatoes (Yukon Gold or Russet, peeled and thinly sliced)
- 1 medium onion (thinly sliced)
- 2 tbsp butter
- 2 cloves garlic (minced)
- 1 (10–12 oz) can condensed cream of mushroom soup or cream of chicken
- 1 cup sour cream
- 1 (1 oz) packet dry French onion soup mix
- 1 cup shredded cheddar or Gruyère cheese (for a more French-style flavor)
- Salt and black pepper to taste
- Fresh parsley (for garnish, optional)
Step-by-Step Instructions
Prep the Oven & Dish: Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with butter or nonstick spray, ensuring your bake won’t stick!
Make the Creamy Base: In a saucepan over medium heat, melt the butter. Add the sliced onions and cook for about 5–7 minutes, until they are softened and slightly golden. Stir in the minced garlic and let that aromatic goodness cook for one more minute.
Combine Ingredients: In a mixing bowl, combine the cooked onion and garlic mixture with the condensed soup, sour cream, and French onion soup mix. Stir until everything is well combined and creamy.
Assemble the Bake: Spread half of the sliced potatoes evenly in the greased baking dish. Top with half of the creamy onion mixture, and sprinkle a little bit of cheese over the top. Repeat the layer with the remaining potatoes, creamy sauce, and end with a generous layer of cheese.
Bake: Cover the dish with aluminum foil and bake it in the preheated oven for 35–40 minutes. After that, remove the foil and bake for an additional 15–20 minutes until the potatoes are tender and the top is bubbly and golden.
Serve: Allow the dish to rest for about 5–10 minutes before serving. If you’d like, garnish with freshly chopped parsley for a touch of color.
Delicious Variations to Try
Add Veggies: Toss in some steamed broccoli or sautéed mushrooms for added nutrition and texture.
Spicy Kick: Incorporate some diced jalapeños or a sprinkle of red pepper flakes for a zesty twist.
Different Cheeses: Switch it up by using different cheeses like fontina or Monterey Jack for a unique creamy flavor.
Herbs: Sprinkle in fresh thyme or rosemary into the creamy base for a fragrant, herbal touch.
Chef Emma’s Helpful Tips
Make Ahead: You can prepare this dish a day in advance! Assemble everything, cover tightly, and refrigerate. Just add a few extra minutes to the baking time.
Ingredient Swaps: If you don’t have cream of mushroom soup, feel free to use cream of chicken or even a homemade cream sauce for a fresher taste.
Uniform Slices: Use a mandolin slicer for perfectly thin potato slices; this will help them cook evenly and become tender.
Storage Suggestions: Leftovers can be stored in an airtight container in the fridge for up to 3 days. For longer storage, freeze portions, and reheat when you need a cozy meal!
