How to Make French Onion Funeral Potatoes

Step 1: Prepare Your Oven and Dish

Start by warming your oven to 350°F and generously spraying a 9×13-inch baking dish with nonstick cooking spray. This simple step ensures your casserole will slide out effortlessly and the edges will bake up wonderfully crisp and golden.

Step 2: Combine the Potatoes, Cheese, and Sour Cream

In a large bowl, mix together the thawed cubed hash browns, melted butter, sharp cheddar cheese, and sour cream until everything is evenly coated and creamy. This mixture is the heart of your French Onion Funeral Potatoes, blending the comforting texture of tender potatoes with the luscious bite of melted cheese and tangy sour cream.

Step 3: Make the Flavorful Sauce

Next, melt butter in a medium non-stick skillet over medium heat. Add your diced yellow onion and sauté for 3 to 5 minutes until soft and sweet. Toss in the minced garlic and cook for another minute to build that classic French onion foundation. Sprinkle in the flour, salt, black pepper, cayenne pepper, and dried mustard, cooking for one more minute to toast the flour and awaken the spices. Finally, whisk in the room temperature milk and chicken broth slowly, stirring continuously until the sauce thickens to a rich, velvety consistency that will cling perfectly to each potato bite.

Step 4: Combine Sauce with Potato Mixture and Bake

Pour the finished sauce over the potato mixture and stir gently to combine everything evenly. Then transfer this heavenly blend into your prepared baking dish and slide it into the oven. Bake uncovered for 45 to 50 minutes, until the casserole is bubbling hot and the edges have turned a lovely golden brown.

Step 5: Fry Your Onions to Perfection

While your casserole is baking, it’s time to make the crispy fried onions that give the French Onion Funeral Potatoes that irresistible crunch. Line a large baking sheet with two layers of paper towels to drain the oil. Heat the vegetable oil in a large saucepan over high heat until it reaches 350°F. Working in batches, gently fry about 1 cup of the thinly sliced onions, stirring occasionally, until they turn a beautiful pale golden color in 2 to 5 minutes. Remove them carefully with a slotted spoon or fine mesh strainer and place them in a single layer on the paper towels. Sprinkle with kosher salt while still hot to flavor the crispy onions perfectly.

Step 6: Top and Serve Immediately

Once your French Onion Funeral Potatoes are out of the oven and smelling amazing, sprinkle your freshly fried onions evenly over the top. This final step adds the perfect textural contrast and that signature French onion flair everyone will adore. Serve it warm and watch how quickly this dish disappears!

How to Serve French Onion Funeral Potatoes

Garnishes

For a touch of freshness, sprinkle freshly chopped parsley or chives over the top of the casserole before serving. These bright green herbs add a burst of color and a subtle herbal note that complements the creamy richness of the potatoes and cheese beautifully.

Side Dishes

French Onion Funeral Potatoes pair incredibly well with roasted or grilled meats like chicken, ham, or brisket. A crisp green salad with a citrus vinaigrette can offer a refreshing contrast, balancing the rich casserole with bright acidity and crunch.

Creative Ways to Present

If you want to impress at your next potluck or family gathering, bake the casserole in individual ramekins for a personalized touch. Alternatively, layer the potato mixture and sauce in a clear glass baking dish so your guests can admire the gorgeous layers before diving in, making the presentation almost as delightful as the taste.

Make Ahead and Storage

Storing Leftovers

Any leftover French Onion Funeral Potatoes should be transferred to an airtight container and refrigerated promptly. They will stay delicious for up to 3 days, allowing you to enjoy that comforting flavor again with minimal effort.

Freezing

You can freeze this casserole before topping it with the fried onions. Wrap the baking dish tightly with aluminum foil or plastic wrap and freeze for up to 2 months. When ready to enjoy, thaw in the refrigerator overnight before baking.

Reheating

Reheat leftovers in the oven at 350°F for about 20 to 30 minutes, covered with foil to keep the moisture in. Add freshly fried onions on top after reheating to restore that wonderful crunch.

FAQs

Can I use fresh potatoes instead of frozen hash browns?

While fresh potatoes can work, frozen hash browns are convenient and ensure the right texture. If using fresh potatoes, be sure to dice and parboil them for even cooking and creaminess.

Is it possible to make this dish vegetarian?

Yes! Simply substitute the chicken broth with vegetable broth to keep that hearty, savory flavor while making it vegetarian-friendly.

How can I make the fried onions less oily?

Make sure your oil is at the right temperature—about 350°F. Fry the onions in small batches to avoid lowering the oil temperature, and drain them thoroughly on paper towels with gentle blotting to remove excess oil.

Can I prepare the fried onions in advance?

Fried onions are best prepared fresh for maximum crunch, but you can make them a day ahead and store them in an airtight container at room temperature. Just be aware they may lose some crispness over time.

What can I substitute for sour cream in this recipe?

You can use Greek yogurt as a tangy, creamy substitute for sour cream. It works well and adds a little nutritional boost without sacrificing flavor.
