Whenever a party gathering, game day kickoff, or holiday celebration rolls around, there is one appetizer that outshines every other dish on the buffet: a sizzling, molten skillet of Warm Creamy Spinach Artichoke Dip. Crowned with a golden-blistered crust of whole-milk mozzarella and aged Parmigiano-Reggiano, this restaurant-favorite recipe delivers an irresistible contrast of bubbly, caramelized cheese on top and a velvety, garlic-infused cream cheese foundation below. Paired with crunchy sourdough garlic bread soldiers fresh from the oven, every dip pulls endless strings of gooey melted cheese that keep your guests hovering around the cast iron until the pan is scraped spotless.
Too many store-bought or slow-cooker spinach dips end up either watery and soupy from trapped vegetable moisture, or cloying and greasy from poor cheese emulsification. The secret to bakery-and-steakhouse perfection is a simple two-phase cast iron method: melt the cream cheese, sour cream, and aromatics on the stovetop to create a silky, unified base, then transfer straight to a blazing oven to bake and broil. Squeezing every trace of liquid from the spinach guarantees the dip remains ultra-thick and scoopable, holding its velvety body without sliding off your bread.

Key Ingredients & Smart Swaps
- Chopped Spinach: Frozen chopped spinach is ideal for convenience—just be sure to thaw and wring it aggressively in a tea towel until bone dry. Fresh Alternative: Sauté 1 lb of fresh baby spinach in olive oil until wilted, cool, squeeze dry, and chop finely.
- Artichoke Hearts: Canned artichoke hearts packed in water provide a delicate, tender bite without conflicting vinegar. Roughly chopping them ensures pleasant textured chunks in every scoop.
- Full-Fat Brick Cream Cheese: Always use brick cream cheese (not whipped spread in tubs, which contains extra water and air). Softening it to room temperature ensures lump-free melting.
- Sour Cream & Real Mayonnaise: Sour cream balances the rich cheese with clean acidity, while a touch of mayonnaise acts as a natural emulsifier, preventing butterfat separation during high baking heat.
- Whole-Milk Mozzarella & Parmigiano-Reggiano: Freshly shredded mozzarella yields luscious, stretchy melt, while aged Parmigiano contributes bold savory umami seasoning.
- Fresh Garlic & Lemon Juice: Four fresh garlic cloves sautéed in the pan give aromatic punch, while a squeeze of lemon juice cuts through dairy heaviness.
Step-by-Step Cooking Walkthrough
1. Squeeze the Spinach Bone Dry: Preheat oven to 375°F (190°C). Place your thawed spinach into a clean kitchen tea towel. Wrap tightly and twist over your sink with both hands, squeezing with maximum pressure. You should expel at least half a cup of murky liquid. Fluff the dry spinach with your fingers.
2. Melt the Stovetop Base: In a 10-inch ovenproof cast iron skillet, heat 1 tablespoon of olive oil over medium-low heat. Sauté minced garlic for 60 seconds until fragrant. Stir in softened cream cheese, sour cream, and mayonnaise until melted into a smooth, glossy satin cream.
3. Fold in Greens & Seasonings: Add the dried spinach, chopped artichokes, lemon juice, red pepper flakes, salt, pepper, 1 cup of mozzarella, and 1/4 cup of parmesan. Stir until the cheeses melt and stretchy ribbons weave through the mixture. Level the top with a spatula.
4. Top, Bake & Broil: Scatter the remaining 1/2 cup mozzarella and 1/4 cup parmesan across the surface. Bake at 375°F (190°C) for 18 to 20 minutes until bubbling. Switch to HIGH broil for 2 to 3 minutes until blistered with deep golden spots. Garnish with parsley and serve piping hot.
3 Chef Secrets for Perfect Results
1. The Tea Towel Wring-Out Is Mandatory: Spinach is over 90% water. If added wet, that liquid releases in the hot oven, pooling into an unappetizing green puddle on top of your dip and breaking the cheese emulsion. Squeezing in a tea towel until no more drops emerge is the single most important step for rich, velvety dip texture.
2. Grate Cheese from Blocks: Pre-shredded bagged mozzarella and parmesan are coated in anti-caking cellulose powders that prevent smooth melting and create a grainy, greasy mouthfeel. Shredding fresh whole-milk mozzarella and grating aged parmesan from a wedge takes 60 seconds and produces vastly superior melt and stretch.
3. Watch the Broiler Closely: Broilers can turn golden cheese into burnt ash in under 60 seconds. Never walk away during the broiling step—keep your oven light on and pull the skillet the moment you see deep amber blisters bubbling across the cheese crust.
What to Serve With Warm Spinach Artichoke Dip
- Toasted Garlic Sourdough Soldiers: Thick crusty baguette or sourdough brushed with garlic butter and toasted golden creates the sturdiest, most luxurious dipping vehicle.
- Artisan Tortilla Chips & Pita Chips: Thick restaurant-style yellow corn tortilla chips or sea salt pita chips add a wonderful salty crunch.
- Fresh Vegetable Crudité: Crisp bell pepper strips, chilled celery batons, carrot spears, and cucumber rounds offer a cool, crisp, low-carb dipping alternative.

Storage, Freezing & Reheating Instructions
- Refrigeration: Allow leftover dip to cool completely. Transfer to an airtight glass container and refrigerate for up to 4 days.
- Oven Reheating (Best Quality): Transfer chilled dip to an oven-safe dish, cover loosely with foil, and warm at 350°F (175°C) for 12 to 15 minutes until steaming and bubbly throughout.
- Quick Microwave Reheating: Reheat individual portions in microwave-safe bowls in 30-second bursts at 70% power, stirring in between to ensure even heating.
- Make-Ahead & Freezing: You can assemble the entire dip in the skillet or baking dish up to 2 days ahead, cover tightly with foil, and refrigerate unbaked. To bake from cold, add 5 to 7 minutes to the baking time. We do not recommend freezing baked dip, as dairy-heavy emulsions can separate upon thawing.
Ingredients
Method
- Preheat oven to 375°F (190°C). Place the thawed chopped spinach into a clean kitchen tea towel or multiple layers of cheesecloth. Wring and twist the towel vigorously over the sink to squeeze out all excess liquid. You should extract at least 1/2 to 3/4 cup of green water. Fluff the dry spinach with a fork.
- In a 10-inch cast iron skillet set over medium-low heat, add 1 tablespoon of olive oil and the minced garlic. Sauté gently for 60 seconds until fragrant without browning.
- Add the softened cream cheese, sour cream, and mayonnaise. Stir with a wooden spoon until the cream cheese melts into a smooth, glossy sauce.
- Fold in the squeezed dry spinach, chopped artichoke hearts, lemon juice, red pepper flakes, kosher salt, black pepper, 1 cup of shredded mozzarella, and 1/4 cup of parmesan. Stir until the cheeses melt and stringy ribbons form throughout the mixture.
- Smooth the top of the dip evenly in the skillet. Scatter the remaining 1/2 cup of mozzarella and 1/4 cup of parmesan evenly over the entire surface.
- Transfer the skillet to the preheated oven and bake for 18 to 20 minutes until the dip is hot and bubbling vigorously along the edges. Switch the oven to Broil on HIGH for 2 to 3 minutes until the cheese crust develops golden-brown blistered spots.
- While the dip bakes, arrange the sourdough baguette slices on a baking sheet. Brush both sides with garlic herb melted butter. Toast in the oven for 8 minutes until crunchy and golden.
- Carefully remove the bubbling hot cast iron skillet from the oven using thick oven mitts. Garnish with chopped fresh parsley and an extra pinch of red pepper flakes. Serve immediately surrounded by warm garlic bread soldiers, baguette rounds, and tortilla chips.

Let us know how it was!Frequently Asked Questions
Can I make this spinach artichoke dip in a slow cooker?
Yes! Combine all the ingredients in your slow cooker, stir well, cover, and cook on LOW for 2 hours until melted and hot. While you won’t get the blistered oven-broiled crust, the dip stays warm and velvety for hours during parties.
Can I use marinated artichoke hearts instead of canned in water?
Yes, but ensure you drain them very thoroughly and pat off excess oil. Marinated artichokes contain vinegar, herbs, and oil that will add extra tang to your dip—so taste before adding any lemon juice.
Why is my spinach dip runny?
Runny dip is almost always caused by trapped moisture in the spinach or artichokes. Make sure to wring out the spinach forcefully in a tea towel until no more liquid drips out, and drain artichoke hearts thoroughly on paper towels before chopping.
