What Goes Into It

The base is frozen cubed hash browns mixed with melted butter, sharp cheddar cheese, and sour cream. That’s your cozy potato layer. Then you make a quick onion sauce by cooking diced yellow onion with garlic, flour, and a few spiceskosher salt, black pepper, cayenne, and dried mustardbefore whisking in chicken broth and whole milk until it thickens.

The crispy onion topping is just thinly sliced yellow onions fried in vegetable oil until golden and crunchy. You sprinkle them with a little kosher salt, and that’s it. They’re sweet, savory, and add the perfect texture contrast.

How to Make It

Start by mixing your thawed hash browns with melted butter, shredded cheddar, and sour cream in a large bowl. Set that aside while you make the sauce. In a medium skillet, melt more butter, cook your diced onion until soft, then add garlic and flour. Whisk in the chicken broth and milk slowly, stirring until the sauce thickens. Pour that into the potato mixture, stir everything together, and pour it into a greased 9×13-inch baking dish.

Bake at 350°F for 45 to 50 minutes until bubbly. While it bakes, heat vegetable oil to 350°F and fry your sliced onions in batches until golden. Drain them on paper towels, sprinkle with salt, and when the casserole comes out of the oven, pile the crispy onions on top.

Step	What You’re Doing	Time
Prep potatoes	Mix hash browns, butter, cheese, sour cream	5 min
Make sauce	Cook onions, garlic, flour; whisk in broth and milk	8–10 min
Bake	Pour into dish and bake at 350°F	45–50 min
Fry onions	Fry sliced onions in batches at 350°F	10–12 min
Finish	Top hot casserole with crispy onions	1 min

Quick Swaps and Tips

If you don’t have sharp cheddar, mild cheddar or Gruyère both work beautifully here. Swap sour cream for Greek yogurt if that’s what you haveit’ll be slightly tangier but still creamy. For a lighter version, use half-and-half instead of whole milk, though the sauce won’t be quite as rich.

Pro Tip: Make sure your oil stays at 350°F between batches when frying onions. If it drops too low, they’ll absorb oil and get soggy instead of crispy.

Ingredient	Swap Options
Sharp cheddar	Mild cheddar, Gruyère, Swiss
Sour cream	Greek yogurt, crème fraîche
Whole milk	Half-and-half, 2% milk
Chicken broth	Vegetable broth, beef broth
Frozen hash browns	Fresh cubed potatoes (parboil first)

How to Serve and Store

Serve this alongside roasted chicken, grilled steak, or a simple green salad. It’s hearty enough to be the main event with a side of roasted vegetables or crusty bread. Leftovers keep in an airtight container in the fridge for up to four daysreheat in the oven at 350°F until warmed through, or microwave individual portions.

The crispy onions will soften a bit once they sit on the casserole, so if you want them extra crunchy, store them separately and add fresh on top when you reheat.

Storage	How Long	Notes
Refrigerator	Up to 4 days	Store in airtight container
Freezer	Up to 2 months	Freeze before adding fried onions
Reheating		Oven at 350°F or microwave until hot
Crispy onions	3–4 days	Store separately in airtight container

How I Finally Nailed French Onion Funeral Potatoes

I burned the onions twice and once forgot the sour cream entirely before I got these French Onion Funeral Potatoes right. My mom laughed at my kitchen disasters, but now this cheesy, oniony comfort dish is exactly what I imagined. Worth every messy attempt.

FAQs ( French Onion Funeral Potatoes )

Can I make this recipe ahead of time?

Yes, you can assemble this casserole up to 24 hours before baking. Cover tightly with foil and refrigerate. Add 10-15 minutes to the baking time if cooking straight from the fridge. The flavors actually develop beautifully overnight.

What type of potatoes work best?

Frozen hash browns or fresh russet potatoes both work wonderfully. If using fresh potatoes, partially cook them first to ensure they’re tender. Yukon Gold potatoes also create a creamy texture that pairs perfectly with the caramelized onion flavors.

How do I prevent the dish from drying out?

Cover with foil for the first 30 minutes of baking, then remove to brown the top. Make sure there’s enough liquid from the soup and sour cream mixture. If it looks dry, add a splash of milk or broth before baking.

Can I use fresh onions instead of French onion soup?

Absolutely! Caramelize 2-3 large yellow onions until golden brown, then mix with cream of mushroom soup and beef broth. This homemade approach gives you more control over the onion flavor and reduces sodium content significantly.

How long do leftovers keep?

Leftovers stay fresh in the refrigerator for 3-4 days when stored in an airtight container. Reheat individual portions in the microwave or warm the whole dish covered in a 350°F oven for 15-20 minutes until heated through.

You’ll love how French Onion Funeral Potatoes turn outcreamy, golden, and topped with crispy onions that crunch with every bite. It takes about an hour start to finish, but most of that is hands-off baking time while your kitchen fills with the smell of caramelized onions and melted cheese. This is the kind of dinner that makes everyone feel settled.

If you want to switch things up, try swapping half the cheddar for Gruyèreit adds a nutty richness that feels a little fancier. You can also make the whole casserole a day ahead, then bake it right before dinner and fry the onions fresh. My mom used to do that for church potlucks, and it saved her sanity every time. Leftovers reheat beautifully in the oven, though I won’t judge if you sneak a cold forkful straight from the fridge.
