Oven-Baked 4-Ingredient Creamed Spinach Potato Bake
My neighbor brought this Oven-Baked 4-Ingredient Creamed Spinach Potato Bake to a church potluck last month, and it disappeared in minutes. Before anyone had even finished their first serving, people were already asking for the recipe. One bite explains why: tender sliced potatoes, creamy spinach, melted cheese, and buttery golden edges come together in one irresistibly cozy casserole.
This is the kind of old-fashioned comfort food that feels right at a church supper, family dinner, holiday table, or casual Sunday gathering. The ingredient list is wonderfully short, but the finished dish tastes far more elaborate than it actually is. The potatoes become tender and creamy as they bake, the spinach adds savory richness and color, and the cheese melts into the layers for a beautifully browned, bubbly finish.
Best of all, this 4-ingredient potato casserole requires very little preparation. Layer everything in one baking dish, cover, bake, uncover, and let the oven do the work. It is hearty enough to satisfy a crowd while being simple enough for a busy weeknight.

Ingredients
2 pounds russet or Yukon Gold potatoes
The potatoes form the hearty foundation of this casserole. Russet potatoes become soft and fluffy as they bake, while Yukon Gold potatoes have a naturally buttery texture and tend to hold their shape beautifully. Peel them and slice them thinly and evenly so every layer cooks at the same rate.
1 package (10 ounces) frozen creamed spinach, thawed
This is the shortcut that gives the casserole its signature creamy flavor. Frozen creamed spinach provides spinach, seasoning, and a rich sauce all in one ingredient, making it possible to create a comforting casserole without preparing a separate cream sauce.
1 cup shredded mozzarella or cheddar cheese
Cheese melts between the layers and forms a deliciously golden top. Cheddar provides a sharper, more pronounced flavor, while mozzarella gives the casserole a milder taste with a wonderfully stretchy melt. Either works beautifully.
2 tablespoons butter, cut into small pieces
Butter adds richness and helps the top develop those irresistible golden, savory edges. Dotting small pieces over the casserole before baking distributes the buttery flavor without requiring any additional preparation.
How to Make Oven-Baked Creamed Spinach Potato Bake
1. Prepare the oven and baking dish
Preheat your oven to 375°F. Lightly butter a medium-sized casserole dish.
Make sure the creamed spinach has completely thawed before assembling the casserole. If it is especially thick, give it a gentle stir so it is easier to spread between the potato layers.
2. Start layering
Spread a thin layer of creamed spinach across the bottom of the prepared baking dish.
Arrange a layer of thinly sliced potatoes over the spinach, keeping the slices as evenly distributed as possible.
Spoon more creamed spinach over the potatoes, then sprinkle with some of the shredded cheese.
Continue building layers of potatoes, creamed spinach, and cheese until everything has been used.
Finish by scattering the remaining cheese over the top and dotting the surface with the small pieces of butter.
3. Bake covered
Cover the casserole tightly with aluminum foil.
Bake for approximately 45 minutes.
The covered baking time allows steam to circulate inside the dish, helping the potatoes soften without allowing the top to brown too quickly.
4. Uncover and brown
Carefully remove the foil and return the casserole to the oven.
Continue baking for another 20 to 30 minutes, or until the potatoes are completely fork-tender and the cheese on top is lightly browned and bubbling.
If the potatoes are still firm in the center, give them additional baking time. Potato thickness and the depth of your casserole dish can affect the total cooking time.
5. Let it rest
Remove the casserole from the oven and allow it to rest for 10 minutes before serving.
This short resting period allows the creamy layers to settle, making the casserole easier to scoop while keeping each serving beautifully rich and cohesive.
Pro Tips for the Best Potato Bake
Slice the potatoes evenly
This is one of the most important steps. Thin, uniform slices cook much more evenly than a mixture of thick and thin pieces. A mandoline can help create consistent slices, but a sharp knife works perfectly well.
Don’t skip the covered baking stage
Keeping the casserole covered during the first part of baking traps steam and helps the potatoes become tender. Removing the foil too early can leave the potatoes undercooked while the cheese becomes overly browned.
Thaw the spinach first
Frozen creamed spinach should be thawed before assembling the casserole. Excess ice or water can interfere with the creamy consistency and increase the baking time.
Choose your cheese according to the flavor you want
For a classic, slightly sharper casserole, reach for cheddar cheese. For a mild, creamy, stretchy topping, use mozzarella. You can also combine the two for the best of both worlds.
Test the center
Don’t judge doneness by the appearance of the cheese alone. Insert a fork or the tip of a small knife into the center. The potatoes should feel completely tender.
Let it rest before serving
Those extra 10 minutes make a difference. The casserole will be less runny, easier to portion, and much more satisfying to serve.
Easy Variations
Add sweet onion
For an extra savory, old-fashioned casserole flavor, add thin slices of sweet onion between the potato layers.
Try Monterey Jack
Monterey Jack melts beautifully and gives the casserole a creamy, mellow flavor.
Make it extra cheesy
If your family loves cheese, sprinkle a little additional cheese over the top during the final 10 minutes of baking for an especially golden finish.
Use Yukon Gold potatoes
For an especially buttery and creamy texture, Yukon Gold potatoes are an excellent choice.
Make-Ahead Instructions
This creamed spinach potato casserole can be assembled several hours ahead of time. Cover the unbaked dish tightly and refrigerate it until you are ready to cook.
Because the casserole will be starting cold, expect to need a few additional minutes of covered baking time. Always check the center for tenderness before serving.
For the best texture, avoid assembling it too far in advance, as the potatoes can release moisture while sitting.

Frequently Asked Questions
Can I use frozen spinach instead of creamed spinach?
The recipe is specifically designed around frozen creamed spinach, which provides both the spinach and creamy sauce. Plain frozen spinach would produce a different texture and would need additional ingredients to create the creamy component.
Can I use cheddar instead of mozzarella?
Absolutely. Cheddar cheese gives the casserole a richer, sharper flavor and creates a beautifully browned topping.
Why are my potatoes still firm?
The most common reasons are thicker potato slices, an overly deep casserole, or insufficient baking time. Cover the dish again and continue baking until a fork slides easily through the center potatoes.
Can I use Yukon Gold potatoes?
Yes. Yukon Gold potatoes are an excellent choice because they have a naturally buttery texture and hold their shape well during baking.
