Lemon fondant potatoes are a bright, citrusy twist on the classic French technique of slowly cooking potatoes in butter and stock until the outside is golden and crisp while the inside turns luxuriously creamy. The lemon adds a fresh, tangy note that cuts through the rich, buttery sauce, making these potatoes feel elegant yet surprisingly simple to make. They’re the perfect side dish for a special dinner, but easy enough for a weeknight treat.
Ingredients
- 4 medium Yukon Gold potatoes (about 2 lb / 900 g), peeled
- 2 tbsp (30 g) unsalted butter, plus 1 tbsp for basting
- 1 tbsp (15 ml) olive oil
- 1 cup (240 ml) low-sodium chicken or vegetable broth
- 1 lemon, zested and juiced (about 1 tbsp zest and 2 tbsp juice)
- 2 sprigs fresh thyme (or 1/2 tsp dried thyme)
- 1 clove garlic, smashed
- 1/2 tsp salt, plus more to taste
- 1/4 tsp black pepper, plus more to taste
- 1 tbsp (15 g) cold butter, cut into small cubes (for finishing)
- Fresh parsley, chopped, for garnish (optional)
Instructions
- Preheat the oven to 425°F (220°C).
- Cut the potatoes into thick cylinders: trim the ends so they stand flat, then cut each potato crosswise into 2-inch (5 cm) thick rounds. Pat them dry with a paper towel.
- Sear the potatoes: In a large oven-safe skillet (cast iron or stainless steel) over medium-high heat, melt the 2 tbsp butter with the olive oil. Place the potato rounds in the skillet in a single layer (cut-side down). Cook without moving for 4–5 minutes, until deeply golden brown. Flip and cook the other cut side for another 4–5 minutes, until golden.
- Add the aromatics: Tuck the thyme sprigs and smashed garlic clove around the potatoes. Sprinkle with salt and pepper.
- Create the braising liquid: Pour the broth into the skillet, then add the lemon zest and juice. The liquid should come about halfway up the sides of the potatoes—add a splash more broth or water if needed.
- Bake: Bring the liquid to a gentle simmer on the stovetop, then transfer the skillet to the preheated oven. Bake uncovered for 25–30 minutes, until the potatoes are fork-tender and the liquid has reduced to a glossy, slightly syrupy sauce.
- Finish and serve: Remove the skillet from the oven. Discard the thyme sprigs and garlic clove. Stir in the cold butter cubes until melted and the sauce is emulsified. Taste and adjust seasoning with more salt and pepper. Garnish with fresh parsley, if using, and serve hot.
Tips
- Choose the right potato: Yukon Golds are ideal because they hold their shape while becoming creamy inside. Waxy red or new potatoes also work, but avoid russets—they may fall apart during braising.
- Don’t crowd the pan: When searing, leave space between the potato rounds so they brown properly, not steam. If your skillet is small, sear in batches.
- Use a good skillet: An oven-safe, heavy-bottomed skillet (cast iron or stainless steel) ensures even browning and safe transfer to the oven. Avoid nonstick with a plastic handle.
- Adjust the lemon to taste: If you prefer a more subtle citrus flavor, use only the zest and half the juice. For a more pronounced tang, add the full juice and a little extra zest.
Serving Suggestions
These lemon fondant potatoes are a fantastic side for roasted chicken, pan-seared steak, or grilled fish like salmon or halibut. They also pair beautifully with a simple green salad or steamed asparagus for a lighter meal. Spoon the lemony pan sauce over the potatoes and your main protein for extra flavor.
Variations
- Herb swap: Replace thyme with rosemary, sage, or oregano for a different aromatic profile.
- Garlic lover’s version: Add 2–3 smashed garlic cloves instead of 1, or toss in a few whole peeled shallots with the potatoes.
- Spicy kick: Add a pinch of red pepper flakes or a small dried chili along with the thyme for a subtle heat.
- Vegan option: Use olive oil instead of butter and a good-quality vegetable broth. For the finishing butter, use a vegan butter substitute or simply omit it—the sauce will still be flavorful.
Storage and Reheating
Leftover lemon fondant potatoes can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place them in a skillet with a splash of broth or water over medium heat, covering with a lid, until warmed through—about 5–7 minutes. You can also reheat in the microwave, but the texture will be softer. For best results, avoid freezing, as the potatoes may become mushy.
Frequently Asked Questions
Can I use other types of potatoes? Yes, you can use other waxy or all-purpose potatoes like red potatoes or white round potatoes. Avoid starchy russets, which tend to break apart during braising.
Why do my potatoes stick to the pan? Sticking usually happens if the pan isn’t hot enough or if you move the potatoes too early. Make sure the oil is shimmering before adding the potatoes, and let them cook undisturbed until they release easily.
Can I make this dish ahead of time? You can sear the potatoes and prepare the aromatics a few hours ahead, but the braising should be done just before serving. The potatoes are best fresh out of the oven, when the texture is perfect.
What if I don’t have an oven-safe skillet? You can sear the potatoes in any skillet, then transfer them to a baking dish along with the broth and aromatics. Cover the dish with foil for the first 20 minutes of baking, then uncover for the last 10 minutes.
Can I double the recipe? Yes, you can double the ingredients, but use a larger skillet or divide between two skillets to avoid overcrowding. Increase baking time by about 5–10 minutes, checking for doneness with a fork.
Is it necessary to peel the potatoes? No, you can leave the skin on for a more rustic look and extra texture. Just scrub them well before cutting.
