1 cup shredded sharp cheddar Mix half mozzarella for stretch.

1 tsp garlic powder Fresh minced garlic works too.

½ tsp smoked paprika Adds depth without heat.

Instructions

Prep the Sweet Potatoes

Toss the cubed sweet potatoes with 1 tbsp olive oil, garlic powder, smoked paprika, salt, and pepper. Spread them evenly in a large, deep skillet or Dutch oven.

Pro Tip: Cut potatoes into uniform ½‑inch cubes for even cooking.

Sauté the Base

Over medium heat, stir‑fry the potatoes for 5‑7 minutes until they start to soften. Add the remaining 1 tbsp olive oil and the fresh spinach; cook until wilted, about 2 minutes.

Pro Tip: If the pan looks dry, splash a splash of water to prevent sticking.

Create the Creamy Sauce

Reduce heat to low. Stir in milk, half of the cheddar, and a pinch of extra salt. Simmer gently for 3‑4 minutes, allowing the sauce to thicken and coat the vegetables.

Pro Tip: Whisk continuously to avoid curdling.

Bake to Perfection

Preheat oven to 375°F (190°C). Transfer the skillet to the oven (or pour into a baking dish) and bake uncovered for 15‑20 minutes, until the top is golden and the potatoes are fork‑tender.

Pro Tip: A quick broil for the last 2 minutes adds extra crust.

Finish & Serve

Remove from oven, let rest 5 minutes, then sprinkle the remaining cheddar on top. Slice, serve hot, and enjoy a comforting, budget‑friendly meal.

Pro Tip: Resting allows the sauce to set, making portions cleaner.

Expert Tips

Tip #1: Use a Heavy‑Bottom Pot

A thick‑walled skillet distributes heat evenly, preventing hot spots that can scorch the sauce.

Tip #2: Add a Crunch

Top the casserole with a handful of toasted breadcrumbs or crushed nuts just before serving.

Tip #3: Freeze for Later

Cool completely, portion, and freeze. Reheat in the oven; add a splash of milk to revive the sauce.

Tip #4: Boost Flavor

Stir in a teaspoon of Dijon mustard or a splash of apple cider vinegar for subtle tang.
