Ingredients You’ll Need
Every ingredient in this French Onion Baked Potatoes Recipe is deliberate, balancing simple pantry staples with flavors that build depth and richness. From the sturdy russets to the indulgent Gruyère, each component plays a key role in crafting the perfect harmony of crispy, creamy, and cheesy deliciousness.
- 4 large russet potatoes: The ideal potato for baking, with a fluffy interior and sturdy skin to hold all the toppings.
- 2 tbsp olive oil: Helps to crisp up the potato skins and adds a subtle fruity flavor.
- Salt and pepper, to taste: Essential for seasoning and bringing out the natural flavors.
- 1 tbsp butter: Creates the perfect base to caramelize the onions with a rich, silky finish.
- 1 medium onion, thinly sliced: The star ingredient, slowly caramelized for sweetness and depth.
- 1 tbsp all-purpose flour: Thickens the onion sauce for a luscious texture.
- 1 cup beef broth (or vegetable broth): Adds savory richness, with beef broth providing deep flavor, while vegetable broth keeps it lighter.
- 1/2 cup heavy cream: Brings creaminess and balances the caramelized onions with silkiness.
- 1/2 tsp thyme (optional): Adds a subtle herbal note that complements the onion’s sweetness perfectly.
- 1/2 cup shredded Gruyère cheese (or Swiss cheese): Melts beautifully with a nutty, slightly sweet taste.
- 1/2 cup shredded cheddar cheese: Adds a sharp tang and extra gooey melt.
- Fresh parsley, chopped (optional): A pop of color and fresh brightness to finish the dish.
How to Make French Onion Baked Potatoes Recipe
Step 1: Prepare and Bake the Potatoes
Start by preheating your oven to 400°F (200°C). Wash and dry your russet potatoes thoroughly – they need to be clean but dry so the skins crisp up nicely. Pierce each potato a few times with a fork, then rub them generously in olive oil before sprinkling salt and pepper all over. This seasoning is key for tasty skins. Place them directly on the oven rack and bake for 45-60 minutes until they’re tender all the way through when poked with a fork.
Step 2: Caramelize the Onions
While the potatoes bake, focus on the magic happening in the skillet. Heat the butter over medium heat and add your sliced onions. Patience is everything here – cook them slowly for 15-20 minutes, stirring occasionally so they brown evenly without burning. If the onions stick, splash in a bit of broth or water to loosen all those delicious browned bits from the pan. The result is sweet, deeply caramelized onions that bring the soul to this recipe.
Step 3: Make the French Onion Sauce
When the onions are perfectly caramelized, sprinkle the flour over them, mixing well to coat. This will help thicken your sauce beautifully. Then, slowly add in the broth, stirring constantly to prevent lumps and create a smooth sauce base. Pour in the heavy cream and stir in thyme if you like that touch of herbaceous complexity. Let it simmer gently for 5-7 minutes until thickened, then season with salt and pepper to taste. This luscious onion sauce is the heart of the French Onion Baked Potatoes Recipe.
Step 4: Assemble the Potatoes
Once your potatoes are done baking and piping hot, carefully cut a slit down the center of each. Use a fork to fluff up the insides slightly, creating a cozy nest for the sauce. Ladle a generous amount of that rich French onion sauce over the potato, ensuring every bite is flooded with flavor.
Step 5: Add the Cheese and Finish Baking
Now it’s time for the ooey-gooey part: sprinkle shredded Gruyère and cheddar cheese on top of each potato. Return the potatoes to the oven for another 5-10 minutes so the cheese melts and bubbles enticingly. The combination of beautiful melted cheese and caramelized onion sauce is pure comfort food magic.
Step 6: Serve and Enjoy
Once golden and bubbly, remove the potatoes from the oven. If you like, sprinkle with fresh chopped parsley for a burst of color and freshness. Serve immediately and watch everyone delight in every warm, cheesy bite.
How to Serve French Onion Baked Potatoes Recipe
Garnishes
A sprinkle of fresh parsley is the classic finish, adding a lively green contrast and a hint of fresh herbal brightness that balances the richness beautifully. For a touch of elegance, you could also add a few thin slices of green onion or a sprinkle of crispy bacon bits.
Side Dishes
This French Onion Baked Potatoes Recipe stands well on its own as a hearty meal but pairs wonderfully with a crisp green salad for freshness or roasted vegetables for extra depth. A simple arugula salad with lemon vinaigrette or steamed green beans with toasted almonds complement the dish perfectly.
Creative Ways to Present
For a fun twist, serve the dish as a bar at your next gathering: bake and fluff mini potatoes or sweet potatoes, set out the French onion sauce and cheese, and let everyone assemble their own. Or, create twice-baked potato halves using this recipe’s method to make individual portions that look beautiful on a platter.
Make Ahead and Storage
Storing Leftovers
Leftover French Onion Baked Potatoes can be stored in an airtight container in the refrigerator for up to 3 days. It’s best to keep the cheese topping separate if you want to maintain the gooey texture when reheating.
Freezing
Freezing is possible but not ideal for fully assembled versions because the texture of potatoes and cheese can change. Instead, freeze the French onion sauce separately for up to 2 months and reheat before assembling with freshly baked potatoes.
Reheating
To bring leftover potatoes back to life, warm them in a 350°F (175°C) oven for 15-20 minutes until heated through and the cheese is melty again. You can also reheat the sauce gently on the stove and spoon over warm potatoes for best results.
FAQs
Can I use sweet potatoes instead of russet potatoes in this French Onion Baked Potatoes Recipe?
Absolutely! Sweet potatoes offer a delightful natural sweetness that pairs beautifully with caramelized onions. Just adjust baking times slightly as sweet potatoes may cook faster or slower depending on size.
What type of cheese works best for French Onion Baked Potatoes Recipe?
Gruyère and cheddar are classic choices due to their meltability and flavor profiles. Gruyère adds a nutty, slightly sweet note, while cheddar provides sharpness. Swiss cheese can be a great substitute too.
Can I make the French onion sauce vegetarian?
Yes! Simply swap the beef broth with vegetable broth for a lighter, vegetarian-friendly version. The flavor remains rich and satisfying thanks to the caramelized onions and cream.
How long should I bake the potatoes before adding the sauce and cheese?
Bake russet potatoes for about 45 to 60 minutes at 400°F until tender. Once soft, you can slice them open, add the sauce, cheese, and then bake for an additional 5 to 10 minutes to melt the cheese perfectly.
Is French Onion Baked Potatoes Recipe good for meal prep?
Yes, it’s a great option for meal prep! You can prepare the potatoes and sauce in advance, then quickly assemble and bake when ready to eat. Just keep cheese topping fresh until final reheating for that gooey, melty finish.

This recipe combines tender oven-baked russet potatoes with caramelized onions in a creamy sauce, finished with a golden, cheesy topping for a deliciously indulgent side or main dish.
Ingredients
Potatoes
- 4 large russet potatoes
- 2 tbsp olive oil
- Salt and pepper, to taste
French Onion Sauce
- 1 tbsp butter
- 1 medium onion, thinly sliced
- 1 tbsp all-purpose flour
- 1 cup beef broth (or vegetable broth for a lighter option)
- 1/2 cup heavy cream
- 1/2 tsp thyme (optional)
Topping
- 1/2 cup shredded Gruyère cheese (or Swiss cheese)
- 1/2 cup shredded cheddar cheese
- Fresh parsley, chopped (optional, for garnish)
Instructions
- Prepare the Potatoes: Preheat your oven to 400°F (200°C). Wash and dry the russet potatoes. Pierce each potato several times with a fork to allow steam to escape during baking. Rub each potato with olive oil and season generously with salt and pepper to enhance the skin’s flavor and crispness.
- Bake the Potatoes: Place the prepared potatoes directly on the oven rack and bake for 45-60 minutes, or until you can easily pierce them with a fork, indicating they are fully cooked and tender inside.
- Caramelize the Onions: While the potatoes bake, melt butter in a large skillet over medium heat. Add the thinly sliced onions and cook, stirring occasionally, for 15-20 minutes until they become golden brown and caramelized. If the onions begin to stick to the pan, add a small splash of water or broth to deglaze and prevent burning.
- Make the French Onion Sauce: Sprinkle the flour over the caramelized onions and mix thoroughly to coat. Gradually pour in the beef broth while stirring constantly to avoid lumps. Stir in the heavy cream and thyme if using. Let the sauce simmer gently for 5-7 minutes until it thickens slightly. Season with salt and pepper to your taste.
- Assemble the Potatoes: When the potatoes are done, remove them from the oven and cut a slit lengthwise down the center of each. Carefully fluff the potato flesh with a fork to create a soft bed for the sauce.
- Add French Onion Sauce: Spoon the prepared French onion sauce generously over each potato, ensuring plenty of caramelized onions and creamy sauce on top.
- Top with Cheese and Bake Again: Sprinkle shredded Gruyère and cheddar cheeses evenly over the sauced potatoes. Return the potatoes to the oven for an additional 5-10 minutes, or until the cheese has melted fully and is bubbly and golden.
- Garnish and Serve: Remove the potatoes from the oven, garnish with freshly chopped parsley if desired, and serve warm. Enjoy your delicious French Onion Baked Potatoes as a satisfying meal or hearty side dish.
Notes
- For a vegetarian version, substitute beef broth with vegetable broth.
- Use vegan butter and non-dairy cream alternatives to make this recipe vegan.
- Caramelizing onions slowly is key to developing the rich flavor of the sauce; be patient and stir often.
- You can prepare the French onion sauce ahead and reheat before assembling the potatoes.
- Adding a pinch of thyme is optional but adds a lovely herbal note to the sauce.
- To save time, microwave potatoes for 5-7 minutes before baking to reduce overall cooking time.
