3 cups fresh spinach, roughly chopped If using frozen, thaw and squeeze excess water.

1 cup shredded Parmesan cheese Grated works best for even crust.

4 large eggs Provides protein and structure.

½ cup whole‑milk milk Use almond or oat milk for dairy‑free.

1 tsp smoked paprika Adds depth; optional.

Salt and freshly ground black pepper, to taste Season in layers for balanced flavor.

Instructions

Pre‑heat & prepare sweet potatoes

Preheat oven to 190°C (375°F). Toss diced sweet potatoes with ½ tsp salt, pepper, and smoked paprika. Spread on a parchment‑lined baking sheet and roast 15 minutes, stirring once, until just tender.

Pro Tip: Cut potatoes uniformly for even cooking.

Sauté spinach

While potatoes roast, heat 1 tbsp olive oil in a large skillet over medium heat. Add spinach, season with a pinch of salt, and cook 2‑3 minutes until wilted. Remove from heat and set aside.

Pro Tip: Do not over‑cook; excess moisture will make the casserole soggy.

Mix wet ingredients

In a large bowl whisk together eggs, milk, and remaining ½ tsp salt. Stir in half of the Parmesan, creating a smooth custard base.

Pro Tip: Whisk gently to avoid incorporating too much air.

Combine & assemble

Fold roasted sweet potatoes and sautéed spinach into the egg mixture. Transfer everything to a greased 9‑x‑13‑inch baking dish, spreading evenly. Sprinkle the remaining Parmesan over the top for a golden crust.

Pro Tip: Pat the sweet potatoes dry with a paper towel before mixing.

Bake to perfection

Bake in the preheated oven for 20‑25 minutes, until the center is set and the top is golden brown. Allow 5 minutes to rest before slicing and serving.

Pro Tip: A quick broil (1‑2 min) adds extra crunch if desired.

Expert Tips

Tip #1: Use a mix of sweet potatoes and carrots

Adding diced carrots boosts sweetness and adds extra beta‑carotene without altering the flavor profile.

Tip #2: Chill before baking for a firmer slice

Refrigerate the assembled casserole 30 minutes; it sets faster, yielding cleaner portions.

Tip #3: Sprinkle a pinch of nutmeg

A dash of warm nutmeg deepens the sweet‑potato flavor without overwhelming the dish.

Storage & Variations

Cool the casserole completely, then refrigerate in an airtight container for up to 4 days. Reheat slices on the stovetop or microwave. Swap spinach for kale, use feta instead of Parmesan, or add cooked bacon for a savory twist.
