Ingredients
What makes French onion funeral potatoes so incredibly addictive?
Frozen cubed hash browns thaw and drain easily, giving you consistent texture without the work of peeling and dicing potatoes yourself. Sharp cheddar cheese melts beautifully and brings bold flavor that mild cheeses can’t deliver. The sauce combines butter, sautéed onions, and garlic with flour to create that thick, creamy base. Cayenne pepper and dried mustard add subtle heat and depth without being spicy.
For the potato base:
- 32 ounces frozen cubed hash browns, thawed and drained
- ¼ cup unsalted butter, melted
- 2 cups sharp cheddar cheese, shredded
- 1½ cups sour cream
For the sauce:
- ¼ cup unsalted butter
- 1 small yellow onion, diced
- 2 teaspoons garlic, minced
- ¼ cup all-purpose flour
- 1 teaspoon kosher salt
- ½ teaspoon black pepper
- ½ teaspoon cayenne pepper
- ½ teaspoon dried mustard
- ½ cup chicken broth (halal-certified), room temperature
- ½ cup whole milk, room temperature
For the fried onion topping:
- 2 large yellow onions, thinly sliced with layers separated
- 4 cups vegetable oil for frying
- ½ teaspoon kosher salt
Step-by-step instructions
1. Preheat your oven to 350°F and spray a 9×13-inch baking dish with nonstick cooking spray. Having everything ready before you start mixing makes the process smooth.
2. Combine the thawed hash browns, melted butter, shredded cheddar cheese, and sour cream in a large mixing bowl. Stir until everything is evenly coated and set aside while you make the sauce.
3. Melt butter in a medium nonstick skillet over medium heat. Add the diced onions and cook for 3-5 minutes until softened and translucent, then add garlic and cook 1 more minute.
4. Sprinkle in the flour, salt, black pepper, cayenne pepper, and dried mustard. Stir constantly and cook for another minute to eliminate the raw flour taste and create a roux.
5. Whisk in the chicken broth (halal-certified) and milk slowly, adding them gradually while stirring constantly. Continue cooking and whisking until the sauce thickens to gravy consistency, about 3-5 minutes.
6. Pour the hot sauce into the potato mixture and mix thoroughly until every piece is coated. Transfer to your prepared baking dish and spread into an even layer.
7. Bake for 45-50 minutes until the casserole is bubbly around the edges and heated completely through. While it bakes, prepare your fried onions.
8. Heat oil in a large saucepan to 350°F using a thermometer to monitor temperature. Line a baking sheet with double paper towels for draining the onions after frying.
9. Fry onions in batches of about 1 cup at a time, stirring occasionally until they turn pale golden brown (2-5 minutes per batch). Remove with a slotted spoon to the paper towels.
10. Sprinkle the fried onions with salt immediately after draining. When the casserole finishes baking, top it evenly with the crispy onions and serve hot.
Essential equipment
9×13-inch baking dish
The standard casserole size gives you perfect depth for the potato mixture without being too shallow. Glass or ceramic distributes heat evenly and shows you when the edges are bubbling.
Large saucepan for frying
A heavy-bottomed pan that holds at least 6 quarts gives you room for oil and onions without overflow. The thick bottom prevents hot spots that can burn your onions.
Fine mesh strainer or slotted spoon
You need a tool that lets oil drain quickly while keeping the delicate fried onions intact. A spider strainer works perfectly for scooping onions without breaking them apart.
Instant-read thermometer (PREMIUM)
Maintaining 350°F oil temperature is crucial for crispy, not greasy, onions. A thermometer takes the guesswork out and prevents under or over-frying every batch.
What to serve with French onion funeral potatoes
Looking for the perfect main dishes and sides to complete your menu?
These cheesy potatoes pair beautifully with roasted turkey (halal-certified), glazed ham (halal-certified), or Herb Butter Turkey. Slow Cooker Turkey Breast makes an easy main course that doesn’t compete for oven space.
Round out your spread with Green Bean Casserole or Roasted Brussels Sprouts with Dijon Aioli. Add Fall Harvest Salad for brightness. Honey Butter Cornbread soaks up that creamy sauce perfectly.
Storage and reheating guide
Refrigerator storage
Store leftover French onion funeral potatoes in an airtight container for up to 3-4 days. Let the casserole cool completely to room temperature before covering to prevent condensation from making the onions soggy.
Freezer storage
Freeze the assembled but unbaked casserole for up to 2-3 months. Wrap tightly in plastic wrap, then aluminum foil. Thaw overnight in the refrigerator before baking as directed, adding the fried onions only after baking.
Reheating instructions
Reheat individual portions in the microwave for 2-3 minutes until heated through. For oven reheating, cover with foil and bake at 350°F for 10-15 minutes. The fried onions won’t be quite as crispy but still taste delicious.
French onion funeral potatoes variations
Want to customize your cheesy potato casserole for different occasions?
Loaded funeral potatoes add crumbled turkey bacon (halal-certified), diced green onions, and extra cheese for over-the-top indulgence. Spicy version doubles the cayenne pepper and adds diced jalapeños to the sauce. Lighter option uses Greek yogurt instead of sour cream and reduces cheese by half.
Three-cheese upgrade combines sharp cheddar, Gruyère, and Parmesan for complex flavor that’s absolutely restaurant-quality. Veggie-loaded stirs in sautéed mushrooms, bell peppers, and spinach. Store-bought shortcut uses canned French’s fried onions if you’re short on time—they work in a pinch though homemade tastes better.
Pro tips and tricks
Want your French onion funeral potatoes to turn out perfect every single time?
Drain thawed hash browns thoroughly by pressing them in a colander or clean kitchen towel because excess moisture makes your casserole watery instead of creamy.
Keep oil at 350°F between batches by waiting a minute for temperature to recover—frying in oil that’s too cool makes greasy, soggy onions instead of crispy ones.
Add onions to hot casserole right before serving so they stay crispy longer—adding them too early makes them lose their crunch in the steam.
Use room temperature liquids for the sauce so they incorporate smoothly without cooling down your roux and creating lumps in the gravy.
Frequently asked questions
Can you make French onion funeral potatoes ahead of time?
Absolutely—assemble the casserole up to 24 hours ahead, cover tightly, and refrigerate. Wait to fry the onions until just before serving. Bake straight from the fridge, adding 5-10 extra minutes to the baking time.
Why are they called funeral potatoes?
The name comes from their traditional appearance at funeral luncheons and potlucks in the American West, especially in Mormon communities. They’re also called “company potatoes” or “party potatoes” for more upbeat occasions.
Can you use shredded hash browns instead of cubed?
Yes, shredded hash browns work but create a different texture that’s more dense and compact. Cubed hash browns hold their shape better and create a lighter, fluffier casserole with more distinct potato pieces.
How do you keep fried onions crispy?
Fry at the correct temperature (350°F), drain thoroughly on paper towels, and add them to the hot casserole right before serving. Storing fried onions in an airtight container at room temperature for up to 2 days keeps them crisp.
Can you skip frying onions and use store-bought?
Definitely—French’s crispy fried onions work in a pinch. Use about 2 cups and add them before the final 10 minutes of baking. Homemade tastes fresher and less processed, but store-bought saves significant time.
What’s the difference between funeral potatoes and hash brown casserole?
They’re essentially the same dish with different names based on regional preferences. Both feature hash browns in a creamy, cheesy sauce with a crunchy topping, though funeral potatoes traditionally use cornflakes while this version uses fried onions.
