The Ingredients

This recipe uses simple, affordable ingredients that come together beautifully.

10 ounces frozen chopped spinach, thawed and well-drained – For color, nutrients, and flavor.
1 cup shredded cheese (cheddar, mozzarella, or a blend) – For a gooey, golden topping.
3 large eggs – For structure and richness.
½ cup heavy cream – For a rich, custardy base.
Salt and pepper, to taste (optional but recommended) – For seasoning.
Cooking spray or a little butter, for greasing the baking dish – For easy release.

Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat your oven to 375°F (190°C). Lightly grease an 8×8-inch baking dish with cooking spray or a little butter so the bake doesn’t stick.

Pro Tip: Grease the dish well so the bake releases easily.

Step 2: Prepare the Spinach

Thaw the frozen chopped spinach and squeeze out as much water as you can using your hands or a clean kitchen towel. The drier the spinach, the less watery your bake will be.

Pro Tip: Squeezing out the water is the most important step—it prevents a watery bake.

Step 3: Whisk the Eggs and Cream

In a medium bowl, whisk together the eggs and heavy cream until smooth. Season with a good pinch of salt and pepper, if using.

Pro Tip: Whisk well to ensure the eggs and cream are fully combined.

Step 4: Add the Spinach and Cheese

Stir the drained spinach into the egg mixture, breaking up any clumps so it’s evenly distributed. Fold in about ¾ cup of the shredded cheese, saving the rest for the top.

Pro Tip: Reserve some cheese for the top—it creates that golden, bubbly crust.

Step 5: Assemble the Bake

Pour the mixture into the prepared baking dish and spread it out evenly. Sprinkle the remaining cheese over the top for a nice golden crust.

Pro Tip: Spread the mixture evenly for uniform baking.

Step 6: Bake to Golden Perfection

Bake for 20–25 minutes, or until the edges are set, the center is just firm, and the top is lightly browned and bubbly. A knife inserted in the center should come out mostly clean.

Pro Tip: Watch the edges—they’ll set first. That’s your signal it’s ready.

Step 7: Rest and Serve

Let the spinach bake rest for 5–10 minutes before serving.

Pro Tip: The rest time allows the bake to set and makes it easier to slice.

Pro Tips for the Best Cheesy Spinach Bake

Squeeze the spinach dry. Excess water makes the bake watery.
Soften the cream cheese. If using, room temperature cream cheese mixes smoothly.
Shred your own cheese. Freshly shredded melts better than pre-shredded.
Whisk the eggs and cream well. For a smooth, custardy base.
Reserve some cheese for the top. For a golden, bubbly crust.
Spread evenly. For uniform baking.
Watch the edges. They’ll set first. That’s your signal it’s ready.
Let it rest. The 5-10 minute rest allows the bake to set.
Serve warm. This is best fresh from the oven.
Make extra. It disappears fast!
