How to Make French Onion Funeral Potatoes: Ultimate Comfort Casserole Recipe

Step 1: Preheat and Prepare

Start by preheating your oven to 350°F and lightly spray a 9×13-inch baking dish with nonstick spray. This little step ensures every bite slides out effortlessly once it’s baked to golden perfection.

Step 2: Mix the Casserole Base

In a spacious mixing bowl, combine the thawed hash browns, melted butter, shredded cheddar cheese, sour cream, diced onion, minced garlic, flour, kosher salt, black pepper, cayenne pepper, dried mustard, chicken broth, and milk. Stir all these ingredients thoroughly until everything’s evenly distributed and the casseroled mix looks creamy and inviting.

Step 3: Transfer to the Baking Dish

Pour the well-mixed casserole base into your prepared baking dish. Using a spatula, gently spread it out so it cooks evenly, promising a perfect texture across the whole pan.

Step 4: Create the Crispy Onion Topping

In a frying pan over medium heat, warm up the vegetable oil until it’s hot enough for frying. Carefully add the thinly sliced yellow onions, cooking them until they turn a gorgeous golden brown and become irresistibly crispy. Once done, remove them with a slotted spoon and sprinkle with kosher salt for that extra burst of flavor.

Step 5: Bake Your Casserole

Place your dish into the preheated oven and bake for approximately 50 minutes. You’ll know it’s ready when the casserole is bubbly and the top turns a beautiful golden color—pure comfort in every bubbling inch.

Step 6: Add the Crowning Crispy Onions

In the last five minutes of baking, take the casserole out and sprinkle your crispy onions evenly on top. Return it to the oven and let the topping brown further, adding that final signature crunch to your French Onion Funeral Potatoes: Ultimate Comfort Casserole Recipe.

FAQs

Can I use fresh potatoes instead of frozen hash browns?

Absolutely! If you prefer fresh potatoes, peel and cube them before parboiling until just tender, then proceed with the recipe as usual. This adds a little extra prep time but fresh potatoes impart a wonderful natural flavor.

Is there a vegetarian version of this casserole?

Yes! Swap the chicken broth for vegetable broth to keep it vegetarian-friendly. The dish remains just as flavorful and comforting without meat-based ingredients.

What type of cheese works best in this casserole?

Sharp cheddar is the classic choice because of its bold flavor and meltability, but you can mix in other cheeses like Gruyère or Monterey Jack for a unique twist that suits your taste.

Can I make this dish gluten-free?

To make it gluten-free, substitute the all-purpose flour with a gluten-free flour blend or cornstarch, and ensure your broth is gluten-free. The taste and texture will still be incredible.
