French Onion Funeral Potatoes bring together the comfort of creamy, cheesy potatoes and the irresistible flavor of crispy homemade fried onions. This dish always disappears fast at gatherings and has become my go-to when I want something that is both nostalgic and a little bit special.

When I first made this, I never thought the homemade onions would make such a difference. Now my family insists I make extra so they can snack on them before dinner.

Ingredients

  • Frozen cubed hash browns: Choose ones with little added seasoning for best results
  • Unsalted butter: Adds richness and helps everything meld Avoid margarine for a creamy texture
  • Sharp cheddar cheese: Buy a block and shred it for better melt and flavor
  • Sour cream: Full fat gives extra creaminess but lite versions work as well
  • Small yellow onion: For sauce depth Look for onions that feel firm and heavy
  • Garlic: Fresher cloves make the sauce more aromatic
  • All purpose flour: Makes the sauce smooth and thick Select an unbleached variety
  • Kosher salt: Enhances all the flavors Choose coarse grain
  • Black pepper: Freshly cracked tastes best
  • Cayenne pepper: Brings a gentle background heat You can add more if you want it spicy
  • Dried mustard: Gives a slightly tangy richness Make sure it smells bright
  • Chicken broth: Look for a low sodium version or homemade for control
  • Whole milk: Room temperature milk blends better in the sauce
  • Large yellow onions: For the topping The more layers the better for fried onions
  • Vegetable oil: Clean high smoke point oil makes crispier onions

Tips

Select good potatoes that are still frozen solid avoid any icy chunks I have found shredding cheese yourself gives a noticeable difference in flavor and melt

Step-by-Step Instructions

Prepare the Oven and Dish:
Set your oven to three hundred fifty degrees Fahrenheit and spray a standard thirteen by nine inch baking dish so nothing sticks later
Mix the Potato Base:
In a big bowl stir together thawed hash browns melted butter sharp cheddar and sour cream Use a sturdy spoon and be gentle so the potatoes stay in cubes Set aside
Make the Creamy Sauce:
Melt butter in a medium nonstick skillet over medium heat Add diced onion and cook slowly for three to five minutes until soft not browned then add minced garlic and stir for an extra minute
Build the Roux and Add Liquids:
Sprinkle in flour salt pepper cayenne and dried mustard Stir well for about a minute to coat the onions with the flour Mixture should look thick not dry
Slowly Pour in Liquids:
Pour in milk and chicken broth a little at a time while whisking constantly to avoid lumps Keep whisking until you have a silky thickened sauce
Combine and Assemble:
Pour the finished sauce over the potato mixture in your big bowl Mix gently until everything is evenly combined Spread this into your prepared baking dish
Bake the Casserole:
Place the dish in your preheated oven and bake for about forty five to fifty minutes Check that the potatoes are hot and bubbly throughout
Prepare Fried Onions While Baking:
Slice large onions very thin and separate the layers Heat vegetable oil in a deep pot to three hundred fifty degrees Dry the onions a bit with a towel for best crispiness Fry in batches for two to five minutes until golden Stir gently to keep them separate Use a slotted spoon to lift them onto layered paper towels
Salt the Onions:
Once all onions are fried and drained sprinkle them evenly with kosher salt so they stay tasty even after baking
Finish and Serve:
Take the hot casserole from the oven and cover the top with a thick layer of the fried onions right away Serve hot and fresh

I never thought fried onions could be a game changer but they add such a deep savory flavor to every bite My kids love helping slice the onions and consider this the best part of making it together

Storage Tips

Leftover casserole stores well in the fridge for up to four days The onions on top will soften a bit but you can re crisp them under the broiler for a few minutes To freeze wrap the cooled casserole well and keep up to two months Reheat straight from frozen until piping hot

Ingredient Substitutions

For the potatoes use diced cooked potatoes or shredded hash browns if you have those on hand If you need a lighter version try using light sour cream and reduced fat cheddar Monterey jack can work as a cheese swap and for a meatless option switch to vegetable broth

Serving Suggestions

These potatoes pair perfectly with roast meats like ham or beef They also work as a main meal with a crisp green salad and steamed veggies I sometimes serve them at brunch with eggs on the side for extra warmth

How to Prepare

Step 01

Preheat oven to 175°C. Grease a 23 x 33 cm baking dish with nonstick spray.

Step 02

In a large bowl, mix thawed potatoes with melted butter, shredded cheddar cheese, and sour cream until thoroughly combined. Set aside.

Step 03

Melt butter in a non-stick skillet over medium heat. Add diced onion and cook until softened, about 3–5 minutes. Stir in minced garlic and cook for 1 minute longer.

Step 04

Stir in flour, kosher salt, black pepper, cayenne pepper, and dried mustard. Cook for another minute, then gradually add whole milk and chicken broth, whisking until smooth. Continue to cook, stirring, until the sauce thickens.

Step 05

Pour thickened sauce over the potato mixture. Stir well to combine and spread the mixture evenly in the prepared baking dish.

Step 06

Bake in the preheated oven for 45–50 minutes, until the casserole is heated through and bubbling.

Step 07

While casserole bakes, line a large baking sheet with two layers of paper towels. In a large saucepan, heat vegetable oil over high heat to 175°C.

Working in batches, fry about 1 cup of onion rings at a time in the hot oil, stirring occasionally, until pale golden brown, about 2–5 minutes per batch. Remove with a slotted spoon and drain on prepared paper towels. Ensure oil returns to 175°C before each new batch.
