Why You’ll Love These Lyonnaise Potatoes
If you’re a fan of rich, buttery flavors with a hint of sweetness, these Lyonnaise Potatoes are for you! This French-inspired dish is the perfect combination of crispy potato slices and caramelized onions, creating a side dish that is both simple and elegant. Whether you’re making a fancy dinner or just want to elevate your weeknight meals, this recipe from Lila Cooks is a must-try.

What Makes Lyonnaise Potatoes Special?
Unlike basic roasted or fried potatoes, Lyonnaise Potatoes have a unique preparation method that brings out deep, caramelized flavors. The secret lies in the slow-cooked onions, which add a rich sweetness that balances the crispy, golden potatoes. This technique transforms a simple potato dish into a restaurant-worthy experience.

The Secret to Perfect Crispy Potatoes
To achieve the perfect crispy texture, you need to follow a few essential steps. First, always start with starchy potatoes like russets—they crisp up beautifully. Second, parboiling the potatoes before frying helps remove excess starch, ensuring they cook evenly. Lastly, cooking them in a combination of butter and olive oil not only prevents burning but also adds layers of flavor.

Pairing Your Lyonnaise Potatoes
These Lyonnaise Potatoes pair wonderfully with a variety of dishes. Serve them alongside a juicy steak, grilled chicken, or a hearty vegetarian dish for a complete meal. Their buttery richness also complements lighter dishes like fresh salads or steamed greens, creating a balanced dining experience.

Common Mistakes and How to Avoid Them
Many home cooks make the mistake of overcrowding the pan, which leads to steaming instead of crisping. To avoid this, cook the potatoes in batches. Another common issue is using the wrong type of potato—avoid waxy varieties, as they don’t develop the same crispy texture. Lastly, be patient when caramelizing the onions; rushing this step will prevent them from achieving that deep, golden-brown sweetness.
Storing and Reheating Tips
If you have leftovers, store them in an airtight container in the fridge for up to three days. To reheat, avoid the microwave, as it will make the potatoes soggy. Instead, warm them in a skillet over medium heat with a little butter or oil to bring back their crispy texture.
