Costco Artichoke Dip Recipe: Creamy Baked Indulgence With Spinach

There’s nothing quite like a warm, creamy dip to bring a crowd together, and this baked artichoke and spinach version delivers every time. I’ve perfected this recipe to mimic the beloved Costco favorite, with a rich, velvety texture that’s impossible to resist.

The secret lies in the balance of ingredients—marinated artichokes, fresh spinach, and a blend of cheeses that melt into a decadent, bubbling dip. It bakes until golden and irresistibly smooth, with just the right amount of garlic and Parmesan for depth.

Serve it hot with crusty bread, tortilla chips, or fresh veggies for dipping. The flavors meld beautifully, creating a dish that’s as comforting as it is impressive.

This is the kind of appetizer that disappears fast, so I always make a double batch.

Ingredients for Costco Artichoke Dip

Pantry staples plus fresh spinach and artichokes create this velvety crowd-pleaser.

The artichokes are key—Costco’s Kirkland brand marinated hearts are perfect for that signature flavor. Look for them in the deli section or canned aisle. Fresh spinach is a must (baby spinach saves time), but frozen works in a pinch—just thaw and drain really well. For the cheeses, full-fat everything. Low-fat versions won’t give you that melty, gooey texture you’re after.

No marinated artichokes? Canned artichoke hearts in water plus a splash of olive oil and lemon juice gets you close. Fresh spinach can be swapped for frozen, but you’ll need to squeeze out all the water. Out of mozzarella? Monterey Jack melts beautifully. Want extra tang? Add a spoonful of ricotta or feta to the mix.

This dip bakes and holds well, so it’s perfect for parties. Keeps 3-4 days in the fridge—reheat in the oven for best texture. Can be prepped a day ahead and baked just before serving (add 5-10 minutes to the baking time if cold).

Step-by-Step Instructions for Artichoke Spinach Dip

Here’s the method. Straightforward, tested, works every time.

Step 1: Prepare the Vegetables and Aromatics

Drain the 14 oz Marinated Artichoke Hearts thoroughly, then chop them into small, bite-sized pieces. I like to pat them dry with a paper towel to remove excess moisture—this prevents the dip from becoming watery.

Chop the 10 oz Fresh Spinach (stems removed) and mince the 3 cloves Garlic Cloves. The spinach doesn’t need to be perfectly uniform, but aim for roughly ½-inch pieces so it distributes evenly throughout the dip.

Step 2: Create the Creamy Base

In a large mixing bowl, combine the 8 oz Cream Cheese (softened), ½ cup Sour Cream, and ½ cup Mayonnaise. Beat with a hand mixer or whisk until completely smooth and free of lumps. This creates the rich, velvety foundation of your dip.

Add the minced garlic, ½ tsp Salt, ¼ tsp Black Pepper, and ¼ tsp Red Pepper Flakes. Mix well to distribute the seasonings evenly. The cream cheese should be at room temperature to blend seamlessly with the other ingredients.

Step 3: Incorporate Cheeses and Vegetables

Stir in 1 cup Parmesan Cheese (freshly grated) and 1 cup Mozzarella Cheese (shredded). The Parmesan adds a sharp, salty depth while the mozzarella ensures that perfect stretchy texture when baked.

Fold in the chopped artichoke hearts and spinach until everything is evenly combined. The mixture will be thick and chunky at this point—that’s exactly what you want before baking.

Step 4: Bake to Bubbly Perfection

Preheat your oven to 375°F. Grease a baking dish (about 8×8 inches) with 2 tbsp Butter, ensuring all surfaces are well coated. This prevents sticking and adds a subtle richness to the dip.

Spread the dip mixture evenly in the prepared dish. Bake for 20-25 minutes until the top is golden brown and the edges are bubbling. The cheese should be fully melted and slightly blistered on top.

If the top browns too quickly, loosely tent with foil for the remaining baking time. Let it rest for 5 minutes before serving to allow the dip to set slightly.

Serving Suggestions for This costco artichoke dip

Bread Pairings

Crusty French baguette slices are my top pick—they toast lightly when dipped and hold up to the richness. I also love sourdough bread bowls for a dramatic presentation. Warm pita bread or naan adds a soft, chewy contrast to the creamy texture. 🔥

Chip Options

Sturdy tortilla chips are perfect for scooping, especially the restaurant-style thick ones. Pita chips add a nice crunch, while bagel chips provide a hearty bite. For a lighter option, baked potato chips work surprisingly well.

Fresh Veggie Dippers

Cut carrot sticks, celery, and bell pepper strips into uniform lengths for easy dipping. I also love cucumber slices and endive leaves for a refreshing contrast. Lightly steam broccoli florets for a warm veggie option.

Creative Serving Ideas

Scoop the dip into hollowed-out sourdough bread for a shareable centerpiece. Serve in a cast iron skillet to keep it warm throughout the party. For individual portions, use ramekins or small oven-safe dishes. 💡

Garnish and Finish

Sprinkle with chopped fresh parsley or red pepper flakes for color and a hint of heat. A drizzle of hot sauce or balsamic glaze adds a tangy contrast. I always serve with extra grated Parmesan on the side for cheese lovers.
