Preparation Steps

1
Poach Potato Slices in FlavorMatch® Broth

In a saucepan, submerge 3 lbs. thinly sliced Idaho potatoes (1/8 inch thick) in 1 pint prepared, cold RC Hearty Foundations® Vegan GF FlavorMatch® Chicken Flavored Base broth. Bring to a boil over medium-high heat.

2
Simmer to Par-Cook

Reduce heat to a simmer and cook until potato slices are par-cooked (slightly flexible but not fully tender). Remove from heat.

3
Fold Cheese Sauce & Pan

Stir 2 quarts prepared RC Instant Yellow Cheese Sauce Mix and a pinch of ground nutmeg into the par-cooked potatoes and broth until evenly blended. Transfer the mixture into a shallow oven-proof baking dish or hotel pan.

4
Top with Panko-Parmesan Crust & Bake

In a small bowl, combine equal parts (50/50 ratio) grated Parmesan cheese and gluten-free panko bread crumbs. Sprinkle topping evenly over the surface to cover the pan completely. Bake in a preheated 350°F oven until the potatoes are tender, the sauce is bubbly, and the top crust is golden brown.

Chef Notes & Value-Added Variations

Flavor Match Broth Seasoning Secret: Par-boiling potato slices directly in RC Hearty Foundations® Vegan GF FlavorMatch® Chicken Flavored Base infuses savory poultry flavor straight into the center of each starch layer while keeping the dish 100% plant-based and gluten-free.

Gruyère Cheese Upgrade: Fold 8 oz. of shredded Gruyère or Swiss cheese into the RC Instant Yellow Cheese Sauce Mix before baking for an authentic French Dauphinoise profile.

Uniform Slicing Tip: Use a mandoline set to 1/8-inch thickness to guarantee even cooking and elegant layered texture throughout the pan.
