Costco Artichoke Dip Recipe: Creamy Spinach and Parmesan Crowd-Pleaser

There’s a reason this warm, creamy dip disappears first at every gathering. I’ve recreated the beloved Costco version with a velvety blend of artichokes, spinach, and parmesan that’s impossible to resist.

The secret lies in the perfect balance of textures—tender artichokes and wilted spinach swimming in a rich, cheesy base. A touch of garlic and a hint of lemon brighten the flavors without overpowering the dish.

This crowd-pleaser bakes into a golden, bubbling masterpiece that’s ready in under an hour. Serve it with crusty bread, crackers, or fresh vegetables for a guaranteed hit.

Whether for game day or a casual get-together, this dip delivers restaurant-quality results with minimal effort.

Ingredients for Costco Artichoke Dip

Rich, cheesy, and packed with spinach and artichokes. This dip brings the party.

The artichokes are the backbone. Costco’s canned artichoke hearts are perfect—already peeled, tender, and packed in water (not oil). Look for the ones in the tall cans. Fresh spinach is ideal, but frozen works in a pinch—just thaw and drain it really well (nobody wants a watery dip). For the Parmesan, a wedge from the deli counter grated fresh tastes infinitely better than pre-shredded.

No time to grate? Pre-shredded mozzarella saves a step, though it melts slightly differently. Out of Worcestershire? Soy sauce plus a dash of lemon gets you close. The hot sauce is flexible—Sriracha or Cholula work too. If you’re not into spice, skip it entirely. Sour cream can be subbed with Greek yogurt (full-fat for best texture).

Assemble it ahead and refrigerate—just add 10 minutes to the baking time. Leftovers keep for 3-4 days in the fridge, and honestly, they’re almost better the next day. Reheat in the oven or microwave, stirring occasionally.

Instructions

Here’s how to nail this dip with minimal effort and maximum flavor.

Step 1: Prep Vegetables and Aromatics

Drain the 14 oz Canned Artichoke Hearts thoroughly, then chop them into small, bite-sized pieces. I squeeze them in a clean kitchen towel to remove every last drop of liquid—this prevents a watery dip. For the 10 oz Fresh Spinach, remove any tough stems and chop coarsely.

Mince the 3 cloves Garlic Cloves finely. The finer the mince, the more evenly the garlic flavor distributes throughout the dip. I use a microplane for this—it creates a paste-like consistency that blends seamlessly into the creamy base.

Step 2: Build the Creamy Base

In a large mixing bowl, beat the 8 oz Cream Cheese until smooth using a hand mixer or wooden spoon. The cream cheese should be at room temperature—this ensures a lump-free base. Add the 0.5 cup Sour Cream, 0.5 cup Mayonnaise, 1 tbsp Lemon Juice, 1 tsp Worcestershire Sauce, and 0.5 tsp Hot Sauce.

Mix until fully combined and silky smooth. This base is the heart of your dip, so take your time here. The mayonnaise adds richness, while the lemon juice and Worcestershire provide that subtle tang that balances the creaminess.

Step 3: Incorporate Cheeses and Seasonings

Stir in the 1 cup Parmesan Cheese and 1 cup Mozzarella Cheese until evenly distributed. I always use freshly grated Parmesan from a block—it melts more smoothly than pre-grated. Add the minced garlic, 0.5 tsp Salt, 0.25 tsp Black Pepper, and 0.25 tsp Red Pepper Flakes.

The red pepper flakes add a gentle heat that builds with each bite. Taste the mixture now and adjust the salt if needed, but remember the cheeses will intensify in flavor as the dip bakes.

Step 4: Fold in Vegetables and Bake

Gently fold in the chopped artichoke hearts and spinach until just combined. You want these distributed evenly without overmixing, which could make the spinach release too much moisture. Transfer the mixture to a baking dish—I use a 9×9-inch dish for even cooking.

Bake at 375°F for 20-25 minutes until the top is golden brown and the edges are bubbling. The dip is done when the center is hot and the cheese is fully melted. If the top browns too quickly, tent it with foil for the remaining time.

Step 5: Rest and Serve

Let the dip rest for 5-10 minutes after removing it from the oven. This allows the mixture to set slightly, making it easier to serve without it running all over the plate. The texture should be creamy but hold its shape when scooped.

Garnish with extra Parmesan or a sprinkle of red pepper flakes if desired. Serve warm with tortilla chips, bread, or crudités. The flavors meld beautifully as it cools slightly, so don’t rush to dig in immediately—though I won’t judge if you do.

Pro Cooking Tips for This Dish

Prevent Watery Dip

Drain the 14 oz canned artichoke hearts completely and squeeze dry in a clean towel. For 10 oz fresh spinach, chop and press out moisture. This step is non-negotiable for that thick, velvety texture we all love.

Room Temperature Cream Cheese

Let the 8 oz cream cheese soften at room temperature for 30-60 minutes. Cold cream cheese creates lumps that never fully incorporate, no matter how hard you mix. I learned this the hard way! 💡

Even Cheese Distribution

Mix 1 cup parmesan and 1 cup mozzarella thoroughly into the base before adding vegetables. This prevents cheese pockets and ensures every bite has that perfect cheesy pull.

Bake Until Bubbly

Look for a golden-brown top and bubbling edges at 375°F for 20-25 minutes. The center should reach 165°F on an instant-read thermometer. Tent with foil if it browns too quickly.

Rest Before Serving

Let it rest for 5-10 minutes after baking. This allows the dip to set slightly, making it easier to serve without running off the chip. The flavors also meld beautifully during this time.

Oven Position Matters

Bake on the middle rack for even heat distribution. I avoid the top rack as it can cause the cheese to brown too quickly before the center is fully heated through. 🔥
