(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Preheat the oven to 375°F (190°C) and grease a 9×13-inch baking dish with butter or cooking spray.
In a large skillet, heat the butter and olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, until they are soft and golden brown (about 15-20 minutes). Add the garlic powder, thyme, salt, and pepper, then stir to combine. Set aside.
In a separate bowl, whisk together the heavy cream, salt, and pepper.
Arrange a layer of sliced potatoes in the prepared baking dish. Spread some of the caramelized onions over the potatoes, followed by a layer of cheese (Gruyère and cheddar). Repeat the layers, ensuring that the top layer is cheese.
Pour the heavy cream mixture evenly over the top of the potatoes and cheese. Cover the baking dish with aluminum foil.
Bake the casserole for 40-45 minutes, or until the potatoes are tender.
Remove the foil and bake for an additional 10-15 minutes until the top is golden brown and the cheese is bubbly.
Garnish with fresh parsley and serve hot.

FAQs

1. Can I use red or yellow potatoes instead of russet potatoes?

Yes, you can use red or yellow potatoes, though russet potatoes work best for their starchy texture, which helps create a creamy, soft interior.

2. Can I prepare this dish in advance?

Yes, you can assemble the dish a day ahead, cover it tightly, and refrigerate. When ready to bake, remove it from the fridge, allow it to come to room temperature, and then bake as directed.

3. Can I make this dish without heavy cream?

Yes, you can substitute heavy cream with half-and-half, whole milk, or a dairy-free cream alternative, though the texture may vary slightly.

4. How do I know when the potatoes are cooked?

The potatoes should be tender when pierced with a fork. If they’re not soft enough after the first bake, continue to bake them covered for another 10-15 minutes.

5. Can I use pre-sliced potatoes for convenience?

Yes, you can use pre-sliced potatoes if you’re short on time. Just make sure to keep the slices uniform for even cooking.

6. Can I freeze French Onion Potato Bake?

Yes, you can freeze this dish after baking. Let it cool completely before covering tightly with plastic wrap and aluminum foil. Freeze for up to 2 months. Reheat in the oven at 350°F (175°C) until fully heated through.

7. Can I use a different type of cheese?

Yes, you can substitute Gruyère with Swiss cheese, mozzarella, or a blend of cheeses. The cheese will change the flavor, but the dish will still be delicious.

8. How can I make this dish spicier?

Add some red pepper flakes or a dash of cayenne pepper to the onion mixture or sprinkle on top before baking for a little heat.

9. Can I make this dish in individual servings?

Yes, you can make single-serving portions by using smaller baking dishes or ramekins. Adjust the cooking time as needed.

10. What main dishes go well with this potato bake?

This potato bake pairs wonderfully with roasted meats like chicken, beef, or pork. It also complements grilled vegetables, steaks, and salads.

Instructions

Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray.
Caramelize the onions: In a large skillet, melt butter over medium heat. Add the sliced onions and cook, stirring frequently, for about 10-15 minutes until the onions are soft and golden brown. Add garlic and cook for another minute until fragrant. Remove from heat.
Prepare the cream mixture: In a bowl, combine the heavy cream, sour cream, thyme, salt, and pepper. Stir in half of the Swiss cheese and all of the Parmesan cheese.
Layer the potatoes: Place a layer of thinly sliced potatoes in the bottom of the prepared baking dish. Top with a layer of caramelized onions. Repeat layers until all potatoes and onions are used, finishing with a layer of the cream mixture.
Top with cheese and breadcrumbs: Sprinkle the remaining Swiss cheese on top, followed by breadcrumbs (if using).
Bake: Cover the dish with foil and bake for 45-50 minutes, until the potatoes are tender. Remove the foil and bake for an additional 10 minutes until the top is golden and bubbly.
Serve: Let the dish rest for 5 minutes before serving. Garnish with fresh parsley.

Notes

You can add cooked bacon or crispy pancetta between the layers for added flavor.
Use a mandoline slicer for evenly sliced potatoes.
If you prefer a lighter version, substitute the heavy cream with half-and-half or use a reduced-fat sour cream.
