I’m so excited to share this delicious baked potato and onion recipe with you all. This dish has been a staple in my household for years, and I just can’t get enough of it.
It’s simple yet flavorful, and the best part is that it’s incredibly easy to make. My kids love it when I serve it for dinner, and my husband always requests it when we’re having a family gathering.
The first time I made this recipe was when my mom came over for a visit. She brought over some beautiful potatoes from her garden, and we decided to bake them with some onions and herbs.
We served them with a side of sour cream and chives, and it was love at first bite. Since then, I’ve experimented with different toppings and seasonings to make it even more delicious.
I’ve found that using high-quality ingredients like fresh herbs and real butter makes all the difference in the flavor and texture of the dish. My family loves it when I serve this recipe for special occasions like holidays or game day parties.
It’s also a great option for a quick and easy weeknight dinner. Plus, it’s super healthy too – potatoes are packed with fiber, vitamins, and minerals, making them a great addition to any meal.

A comforting and easy dish featuring tender baked potatoes and sweet caramelized onions. This simple recipe makes a perfect side dish or a light vegetarian main course.
4 medium russet potatoes (about 2 pounds), scrubbed and thinly sliced into 1/4-inch rounds
2 large yellow onions, thinly sliced into half-rings
3 tablespoons olive oil
1 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon dried thyme
1/2 cup grated Parmesan cheese (optional)
👨🍳Directions
1Preheat your oven to 400 degrees Fahrenheit.
2In a large mixing bowl, combine the sliced potatoes and onions with olive oil, salt, pepper, and dried thyme.
3Toss everything together until the vegetables are evenly coated with the oil and seasonings.
4Arrange the potato and onion mixture in an even layer in a 9×13 inch baking dish.
5Cover the dish tightly with aluminum foil and bake for 45 minutes.
6The potatoes should begin to soften and release steam.
7Remove the foil and continue baking for another 25 to 30 minutes, or until the potatoes are tender when pierced with a fork and the edges are golden brown.
8If using Parmesan cheese, sprinkle it over the top during the last 5 minutes of baking and let it melt.
9Remove the dish from the oven and let it rest for 5 minutes before serving.
10The potatoes will be tender and the onions will be sweet and caramelized.
For extra flavor, add 2 minced garlic cloves to the oil mixture. You can also substitute sweet potatoes for a different taste. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.

❓ Frequently Asked Questions About Baked Potato and Onion Casserole
Q1: What type of potatoes are best for baking?
A1: Russet or Idaho potatoes work well for baking as they have a dry, starchy texture that holds up well to high heat. You can also use Yukon gold or red potatoes if you prefer a sweeter flavor.
Q2: How do I know if my onions are cooked through?
A2: To check if your onions are cooked through, simply insert a fork or knife into one of the onions – if it slides in easily, they’re done. You can also check by cutting one of the onions in half – if they’re tender and caramelized, they’re ready.
Q3: Can I use pre-made seasoning blends instead of making my own spice mix?
A3: While you can use pre-made seasoning blends, I highly recommend making your own spice mix from scratch using dried herbs like thyme, rosemary, or oregano. This will give your dish a more authentic flavor that’s hard to replicate with store-bought blends.
Q4: How do I prevent my potatoes from becoming too brown while baking?
A4: To prevent your potatoes from becoming too brown while baking, try covering them with foil or parchment paper during the last 30 minutes of cooking. This will help retain moisture and prevent excessive browning.
Q5: Can I make this recipe in advance and store it in the fridge or freezer?
A5: Yes, you can make this recipe in advance – simply prepare the potatoes up to 24 hours in advance, then store them in an airtight container in the fridge until ready to serve. For longer storage (up to 3 months), freeze individual portions wrapped tightly in plastic wrap or aluminum foil.
