Ingredients
Jammy caramelized onions plus gooey Gruyère = a dreamy baked potato.
For the Potatoes
- 4 medium russet potatoes (8 to 10 ounces each)
For the Onion Mixture
- 1 pound yellow onions (about 1 large or 2 medium)
- 1/2 small bunch fresh thyme (about 10 sprigs), plus more for serving
- 1 clove garlic
For the Cheese Topping
- 2 ounces Gruyère cheese
For Cooking
- 4 tablespoons unsalted butter, divided
- 1/2 teaspoon kosher salt, plus more for the potatoes
- 1/2 teaspoon freshly ground black pepper, plus more for the potatoes
- 1 tablespoon all-purpose flour
- 1 cup beef broth
- 1/2 teaspoon balsamic or apple juice vinegar

How to Make Cheesy French Onion Baked Potatoes
Step 1: Preheat the Oven
Arrange one oven rack 6 to 8 inches from the broiler and another in the middle. Heat your oven to 400°F.
Step 2: Bake the Potatoes
Prepare your russet potatoes by scrubbing them clean. Cut a cross shape about 1/4-inch deep into each potato while leaving a half-inch border intact. Place them cut-side up directly onto the middle rack of the oven. Bake until they are very crisp on the outside, which will take about 2 hours.
Step 3: Prepare Onions and Thyme
With about 30 minutes left on the potato timer, halve and thinly slice your yellow onions (about 4 cups total). Pick leaves from half a small bunch of fresh thyme until you have approximately 1 tablespoon. Mince one garlic clove. Grate two ounces of Gruyère cheese using the large holes of a box grater (this should yield heaping 1/2 cup).
Step 4: Caramelize Onions
Melt two tablespoons of unsalted butter in your cast iron skillet over medium heat. Add in your sliced onions, thyme, kosher salt, and black pepper. Stir frequently with a wooden spoon while reducing heat if necessary. Cook until the onions are soft and deeply golden-brown—this should take about 25 to 30 minutes.
Step 5: Create Sauce Base
Add minced garlic and one tablespoon of all-purpose flour to your onion mixture. Stir until well incorporated; it should leave a film on the bottom of the skillet and start to brown after about one minute. Pour in one cup of beef broth while scraping up any browned bits from the skillet’s bottom. Increase heat back to medium if lowered during onion cooking. Bring this mixture to a boil and let simmer until thickened enough to coat the back of a spoon—around three minutes.
Step 6: Season Onion Mixture
Remove your pan from heat. Stir in half a teaspoon of balsamic or apple juice vinegar. Taste your onion mixture and adjust seasoning with additional kosher salt and black pepper if needed.
Step 7: Open Up Baked Potatoes
Carefully remove baked potatoes from the oven using tongs and place them on a baking sheet. Cut deeper into each cross shape made earlier. Gently squeeze opposite ends together to open them up slightly; this releases steam while exposing some flesh inside.
Step 8: Final Bake with Toppings
Return opened potatoes back onto the lower rack of your oven for another ten minutes. After this time, remove them again and push opposite ends together one more time to fully open each potato. Cut remaining two tablespoons of unsalted butter into four pieces—place one piece in each potato along with pinches of kosher salt and black pepper. Evenly distribute onion mixture over each potato (about 1/4 cup per potato) before topping with grated cheese.
Step 9: Broil until Golden Brown
Change oven setting to broil mode. Move baking sheet containing potatoes to upper rack and broil until cheese is melted, bubbly, and golden brown in spots—this will take approximately three to four minutes. If desired, garnish with more fresh thyme leaves before serving.

- Skipping the Potato Prep: Not scrubbing or cutting the potatoes can lead to a less flavorful and unevenly cooked dish. Always clean and score your potatoes properly before baking.

- Ignoring Seasoning: Not seasoning enough can make your dish bland. Remember to taste and adjust salt and pepper throughout the cooking process.
- Using Cold Ingredients: Adding cold butter or cheese directly to hot potatoes can affect melting. Let these ingredients come to room temperature before adding them.
