Instructions

Prep the potatoes

Toss diced potatoes with a pinch of salt and a drizzle of oil. Spread them on a baking sheet and roast at 400°F (200°C) for 15 minutes, until just tender but not browned.

Pro Tip: Cutting potatoes uniformly ensures even cooking.

Sauté garlic & spinach

In a skillet, heat 1 tbsp oil over medium heat. Add minced garlic, cooking 30 seconds until fragrant. Stir in the drained spinach, season lightly, and cook 3‑4 minutes until excess moisture evaporates.

Pro Tip: Don't over‑cook; you want the spinach bright and slightly crisp.

Combine the base

In a large mixing bowl, whisk milk with a pinch of salt and pepper. Fold in the roasted potatoes, sautéed spinach‑garlic mixture, and half of the shredded cheddar. The mixture should be moist but not soupy.

Pro Tip: A splash more milk can be added if the blend feels dry.

Bake to perfection

Transfer the mixture to a greased 9‑x‑13‑inch baking dish. Sprinkle the remaining cheddar evenly on top. Bake at 375°F (190°C) for 20‑25 minutes, until the cheese is melted, golden, and the casserole is bubbling.

Pro Tip: If the top browns too quickly, cover loosely with foil.

Rest & serve

Allow the casserole to rest for 5‑10 minutes before slicing. This helps the layers set, making portions easier to serve. Garnish with a sprinkle of fresh parsley if desired.

Expert Tips

Tip #1: Use a mix of potatoes

Combining Yukon Gold (creamy) with Russet (fluffy) gives a balanced texture that holds up during baking.

Tip #2: Drain spinach thoroughly

Excess water makes the casserole soggy; press the thawed spinach in a clean kitchen towel.

Tip #3: Add a crunchy topping

Mix breadcrumbs with a teaspoon of melted butter and sprinkle over the cheese for extra crispness.

Storage & Variations

Refrigerate leftovers in an airtight container for up to 3 days; reheat in the oven or microwave. For a protein boost, fold in cooked chicken, bacon, or canned beans. Swap cheddar for mozzarella or a dairy‑free cheese for a different flavor profile.

Frequently Asked Questions

Yes. Blanch fresh spinach briefly, then squeeze out water. It provides the same flavor and nutrients, though the texture may be slightly softer.

Ensure the spinach is well‑drained and the potatoes are pre‑roasted. Adding a light dusting of breadcrumbs on top also absorbs excess moisture.

Swap the milk for almond or oat milk and use a vegan cheese or nutritional yeast. The flavor remains rich and satisfying.
