How to Make Spinach Artichoke Au Gratin Potatoes

Creating this magnificent Spinach Artichoke Au Gratin Potatoes dish is a labor of love, but one that rewards you with unparalleled flavor. Follow these detailed steps to achieve perfection.
- Preheat and Prep: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Make sure your potatoes are peeled and sliced uniformly thin; a mandoline is excellent for this.
- Start the Roux: In a large saucepan or Dutch oven, melt the butter over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant, being careful not to burn it.
- Whisk in Flour: Sprinkle the flour over the garlic and butter, whisking constantly for 1-2 minutes to create a smooth roux. This will be the base for your creamy sauce.
- Add Liquids: Gradually whisk in the warmed milk and heavy cream. Continue whisking until the sauce thickens and comes to a gentle simmer, about 5-7 minutes.
- Season the Sauce: Remove from heat. Stir in the salt, black pepper, and nutmeg (if using). This creamy sauce is the heart of your Spinach Artichoke Au Gratin Potatoes.
- Incorporate Spinach & Artichokes: Gently fold in the squeezed dry spinach, chopped artichoke hearts, 1/2 cup of Gruyere cheese, and 1/4 cup of Parmesan cheese into the sauce. Stir until well combined.
- Layer the Potatoes: Arrange about one-third of the thinly sliced potatoes in an even layer at the bottom of the prepared baking dish.
- Pour and Repeat: Pour about one-third of the spinach artichoke cream sauce over the potatoes, spreading evenly. Repeat this layering process twice more, ending with a final layer of sauce.
- Cheese Topping: Sprinkle the remaining 1/2 cup Gruyere, 1/4 cup Parmesan, and all of the mozzarella cheese over the top of the au gratin.
- Bake to Golden Perfection: Cover the baking dish loosely with aluminum foil and bake for 40 minutes. Remove the foil and bake for an additional 20-30 minutes, or until the potatoes are tender when pierced with a fork, and the top is beautifully golden brown and bubbly.
- Rest and Serve: Let the Spinach Artichoke Au Gratin Potatoes rest for 10-15 minutes before serving. This allows the sauce to set and makes for easier, cleaner servings.
Fun Twists & Serving Ideas

Our classic Spinach Artichoke Au Gratin Potatoes are phenomenal as is, but here are some delightful variations and serving suggestions to elevate your culinary experience:
- Protein Power-Up: For a heartier meal, add cooked, shredded chicken or diced ham to the layers.

- Cheese Lover’s Dream: Experiment with different cheese blends! Smoked gouda, sharp cheddar, or even a touch of goat cheese can add intriguing complexity.
- Herbal Infusion: Fresh thyme, rosemary, or chives finely chopped and added to the sauce or as a garnish will brighten the flavors.
- Serving Suggestions: These creamy potatoes are the perfect accompaniment to roasted chicken, grilled steak, baked salmon, or even as a standalone vegetarian main course with a crisp green salad.
FAQ
Have questions about making the perfect Spinach Artichoke Au Gratin Potatoes? We’ve got answers!
Q: Can I prepare Spinach Artichoke Au Gratin Potatoes ahead of time?
A: Yes! You can assemble the dish completely, cover it tightly, and refrigerate for up to 24 hours. Add an extra 10-15 minutes to the baking time if baking from cold, and ensure the potatoes are fully tender.
Q: What kind of potatoes are best for au gratin?
A: Russet potatoes are excellent for this Spinach Artichoke Au Gratin Potatoes recipe due to their starch content, which helps thicken the sauce and create a creamy texture. Yukon Golds or even a waxy potato like red bliss can work, but Russets provide that classic comfort.
Q: How do I ensure my potatoes cook evenly and are tender?
A: The key is thin, uniform slices. A mandoline slicer is highly recommended. Also, make sure your sauce is hot when you pour it over the potatoes, and cover the dish for the initial baking period to steam the potatoes.
Q: Can I use fresh spinach instead of frozen?
A: Absolutely! You’ll need about 10-12 oz of fresh spinach. Sauté it until wilted, then squeeze out as much excess liquid as possible before adding it to the sauce.
