I first discovered this incredible fusion when I was experimenting in my kitchen on a rainy Sunday afternoon. Traditional funeral potatoes had always been a family favorite, but I wanted to elevate them somehow. The inspiration struck when I opened my pantry and saw a packet of French onion soup mix sitting next to my usual ingredients. The combination seemed natural - both dishes are ultimate comfort foods, so why not combine them? As I layered the creamy hash browns with the French onion mixture and topped everything with a blend of cheeses, I could already envision the amazing flavors that would develop. The first bite exceeded all my expectations - the sweet, caramelized onions provided the perfect contrast to the creamy potatoes, while the melted cheese brought everything together in perfect harmony. This recipe has become my go-to for impressing guests while still delivering that homestyle comfort everyone craves.
Why I love this recipe
What I absolutely love about this recipe is how it takes two beloved classics and creates something entirely new and exciting. The French onion flavors add such depth and sophistication to traditional funeral potatoes without losing that comforting, homestyle appeal we all crave. Every time I make this dish, I'm amazed by how the caramelized onions become perfectly crispy on top while the potato base stays incredibly creamy underneath. It's that textural contrast that makes each bite so satisfying. The cheese melts into every crevice, creating pockets of gooey goodness throughout the casserole. But beyond the incredible taste, I love how this recipe brings people together. It's become my signature dish for potlucks, and I always see people going back for seconds and thirds. There's something about comfort food that just makes people happy, and this elevated version never fails to impress while still feeling like a warm hug on a plate.
What You Need From Your Kitchen
- Hash Browns: Thaw completely and drain excess moisture before mixing
- French Onion Soup Mix: Provides the signature French onion flavor throughout the casserole
- Sour Cream: Mix with heavy cream to create the creamy base
- Cheddar Cheese: Shred fresh for best melting and reserve some for topping
- Mozzarella Cheese: Adds extra stretchy, melty texture to the dish
- Butter: Melt and drizzle over top before baking for golden color
Let's Make These Together
- Prepare the potato base mixture
- Start by combining your thawed hash browns with the French onion soup mix, sour cream, and heavy cream in a large bowl. Make sure everything is evenly distributed so every bite has that amazing French onion flavor. The mixture should be creamy but not too wet.
- Layer in the cheeses strategically
- Fold most of your cheddar and mozzarella into the potato mixture, but save some for the top. This creates layers of cheesy goodness throughout the casserole while ensuring you get that beautiful golden top we all love.
- Create the perfect golden top
- Spread your mixture in the baking dish, then drizzle with melted butter and top with reserved cheese. The butter helps create that gorgeous golden color while the cheese on top gets perfectly bubbly and crispy.

Switch Things Up
I'll never forget the first time I decided to experiment with my grandmother's funeral potato recipe. It was for a family reunion, and I was tired of making the same old version everyone expected. I had some French onion soup mix in my pantry and thought, why not? As I caramelized those onions and watched them turn golden brown, the kitchen filled with the most incredible aroma. When I pulled that casserole out of the oven, with the onions perfectly crispy and the cheese bubbling, I knew I had created something special. My uncle took one bite and declared it the best funeral potatoes he'd ever tasted. Now it's become my signature dish for every family gathering.
Perfect Pairings
These French Onion Funeral Potatoes pair beautifully with roasted meats like prime rib or herb-crusted chicken. The rich, creamy texture complements grilled vegetables perfectly, while the French onion flavors enhance any beef dish. Serve alongside a crisp green salad with vinaigrette to cut through the richness, or pair with roasted Brussels sprouts for a complete comfort meal. They're also fantastic with glazed ham during holiday gatherings.

Frequently Asked Questions

You can substitute with caramelized onions mixed with beef bouillon powder, or make your own mix with onion powder, beef bouillon, and dried herbs like thyme.

Absolutely! Peel and grate 2 pounds of russet potatoes, then squeeze out excess moisture with a clean kitchen towel before proceeding with the recipe.
