Ingredients

• Potatoes – 4 large potatoes, peeled and sliced thinly (about 1/4-inch thickness). Russet or Yukon Gold potatoes work best for their texture. These varieties provide a creamy interior and crispy exterior when roasted.
• Onions – 2 large onions, thinly sliced. Yellow onions are ideal for their sweet flavor when caramelized, but red onions can add a beautiful color contrast. The natural sugars in the onions enhance the dish’s overall sweetness.
• Olive oil – 3 tablespoons. Opt for extra virgin olive oil for a richer flavor profile. This oil not only adds flavor but also helps achieve that perfect crispy texture.
• Butter – 2 tablespoons. Choose unsalted butter to control the seasoning better. The butter adds a richness and depth of flavor that complements the olive oil.
• Garlic – 3 cloves, minced. Fresh garlic is preferable, but garlic powder can be used in a pinch. The garlic infuses the dish with aromatic notes that enhance the potatoes and onions.
• Fresh thyme – 2 teaspoons, finely chopped (or substitute 1 teaspoon dried thyme). The fresh version adds a greater depth of flavor. Thyme’s earthy notes pair beautifully with the caramelized onions.
• Salt and pepper – to taste. Start with 1 teaspoon of salt and 1/2 teaspoon of black pepper, adjusting as needed. These basic seasonings bring out the natural flavors of the dish.
• Parmesan cheese – 1/4 cup, grated (optional for a creamy potato and onion dish). For a nuttier flavor, consider freshly grating the cheese yourself. The cheese adds a salty, umami element that enriches the dish.
• Fresh parsley – for garnish, chopped. Adds a fresh, vibrant finish to the dish. The parsley not only provides color but also a hint of fresh flavor that brightens the plate.

Note: Feel free to adjust the quantities based on the number of servings you need. This recipe is quite forgiving and can be easily scaled up or down. For a smaller gathering, simply halve the ingredients or double them for a larger crowd. Check out our related guide for more tips.

Steps / Instructions

1. Preheat your oven to 400°F (200°C). This ensures a perfect roasting environment for the potatoes. A preheated oven helps in achieving that desirable crispiness. The high heat allows for the caramelization of natural sugars, enhancing the dish’s flavor.
2. In a large mixing bowl, combine the sliced potatoes and onions. Drizzle with olive oil and melted butter, ensuring each slice is coated. Sprinkle with garlic, thyme, salt, and pepper. The combination of butter and olive oil provides a balanced flavor with a crisp finish. The oil and butter mixture helps in even roasting.
3. Toss the mixture gently using your hands or a large spoon to ensure even distribution of seasoning. This step is crucial for uniformity in flavor and cooking. Be gentle to avoid breaking the potato slices.
4. Transfer the mixture to a large baking dish or a sheet pan. Spread it out in an even layer to promote even cooking. A crowded pan will steam the vegetables instead of roasting them, which can lead to a soggy texture. Ensure that the potatoes and onions are in a single layer.
5. Roast in the preheated oven for 35-40 minutes, stirring halfway through, until the potatoes are tender and golden brown. Look for crispy edges and a soft interior as your visual cue. Stirring halfway through ensures even cooking and prevents burning. The aroma of roasting potatoes and onions will fill your kitchen.
6. If using, sprinkle the Parmesan cheese over the potatoes during the last 5 minutes of cooking to allow it to melt and create a creamy texture. This adds a rich, savory layer to the dish. As the cheese melts, it forms a delightful crust.
7. Once out of the oven, let the dish rest for a few minutes. Garnish with chopped parsley before serving. Resting allows the flavors to meld, and the garnish adds a pop of color and fresh taste. The final dish should be visually appealing with a vibrant green accent.

For a more robust flavor, consider adding a splash of white wine or chicken stock to the baking dish for the last 10 minutes of cooking. This adds a depth of flavor and can help keep the dish moist.

Tips & Tricks

• For the best results, choose starchy potatoes like Russet or Yukon Gold, as they crisp up nicely. Waxy potatoes like Red Bliss or Fingerlings won’t provide the same texture. Starchy potatoes absorb flavors better.
• If you prefer a sautéed version, cook the potatoes and onions separately in a skillet over medium heat until tender, then combine them. This method gives a different texture and is faster. It’s perfect for a quick side dish.
• To make ahead, prepare the mixture and store it in the refrigerator for up to 24 hours before roasting. This can be a real time-saver for busy evenings or when entertaining guests. Allow the mixture to come to room temperature before baking for even cooking.
• Avoid overcrowding the baking dish; it ensures the potatoes roast instead of steam. Spread them in a single layer for the best results. This technique is key to achieving crisp, well-cooked potatoes.
• Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven to maintain crispiness. Microwaving can make them mushy, so reheating in the oven is preferable. A hot oven will revive the dish’s texture.
• Consider adding a drizzle of balsamic glaze just before serving for an added burst of flavor and color. This adds a sweet and tangy dimension to the dish.

Variations

• Vegan Option: Substitute butter with a plant-based alternative and omit Parmesan cheese or use a vegan cheese. Nutritional yeast can also be used to add a cheesy flavor without any dairy. This makes the dish suitable for a wider audience.
• Spicy Twist: Add a teaspoon of red pepper flakes for a kick. Consider using cayenne pepper for a more intense heat level. Spices can elevate the dish for those who enjoy heat.
• Herbaceous Flavor: Experiment with different herbs like rosemary or oregano for varied flavor profiles. Dill or chives can also add a fresh, unique twist. Fresh herbs can completely change the dish’s character.
• Cheese Lover’s: Mix in some shredded cheddar or Gruyère with the Parmesan for an extra cheesy delight. Cheese enthusiasts will appreciate the complex flavors.

Serving Suggestions

These Easy Potatoes with Onions make a versatile side dish. Pair them with a main course like Better-Than-Takeout Black Pepper Beef for a complete meal. For a lighter option, serve alongside a Fresh Strawberry Spinach Salad. For a more indulgent experience, try them with a Comfort Chicken Pot Pie Pasta. These combinations enhance the dish’s flavors and create a balanced meal.

These potatoes also go wonderfully with a simple roast chicken or grilled fish, providing a hearty yet not overpowering accompaniment. Consider serving them at brunch with poached eggs and a side of crispy bacon for a satisfying start to your day. The flexible nature of the dish allows it to complement various cuisines and meals.
