Instructions

Parboil the Potatoes

Place diced potatoes in a pot of salted water, bring to a boil, and simmer 8‑10 minutes until just tender. Drain well and set aside; they will finish cooking in the oven, preserving a fluffy interior.

Pro Tip: A quick ice‑water rinse stops cooking and prevents mushiness.

Sauté Spinach & Garlic

In a large skillet, melt 1 tbsp butter over medium heat. Add minced garlic, cooking 30 seconds until fragrant. Toss in spinach, stirring until wilted, about 2‑3 minutes. Remove from heat and set aside.

Pro Tip: If using frozen spinach, squeeze out excess moisture before adding.

Create the Creamy Sauce

In a mixing bowl, whisk together Greek yogurt, cream cheese, melted butter, grated Gruyère, nutmeg, salt, and pepper until smooth. Fold in the sautéed spinach, then gently stir in the parboiled potatoes, coating each piece evenly.

Pro Tip: Warm the yogurt slightly to prevent curdling.

Bake to Golden Perfection

Transfer the mixture to a greased 9‑x‑13‑inch baking dish. Sprinkle a thin layer of extra Gruyère on top. Bake in a pre‑heated 375°F (190°C) oven for 30‑35 minutes, until the surface is bubbling and lightly browned.

Pro Tip: Let the casserole rest 5 minutes before cutting; it firms up for cleaner slices.

Serve Warm

Slice the casserole into generous portions and serve straight from the dish. Pair with a crisp orange juice or a hot herbal tea for a balanced, energizing breakfast that brightens even the coldest morning.

Pro Tip: Add a sprinkle of fresh chives for a pop of color and mild onion flavor.

Expert Tips

Tip #1: Use a Hand Mixer

A hand mixer quickly smooths the yogurt‑cheese blend, preventing lumps and ensuring a uniform coating for every potato cube.

Tip #2: Cool Potatoes Slightly

Allow boiled potatoes to cool for 5 minutes before mixing; this reduces steam, keeping the sauce from thinning too much.

Tip #3: Add Crunch

For texture, sprinkle toasted breadcrumbs or crushed pork rinds on top during the last 10 minutes of baking.

Storage & Variations

Cool the casserole completely, then refrigerate in an airtight container for up to 3 days. Reheat portions in the oven at 350°F (175°C) for 15 minutes. Swap spinach for kale, or add cooked bacon bits for a smoky twist. For a vegan version, replace dairy with cashew cream and nutritional yeast.
