½ cup sour cream.
⅓ cup mayonnaise.
1½ cups freshly grated mozzarella cheese.
½ cup freshly grated Parmesan cheese.
3 garlic cloves, finely minced.
¼ cup whole milk.
½ teaspoon onion powder.
¼ teaspoon ground black pepper.
¼ teaspoon crushed red pepper flakes, optional.
¼ teaspoon salt, or to taste.

Ingredient Notes

Spinach: Frozen chopped spinach is convenient, but it must be thawed and squeezed very dry.

Artichoke hearts: Use canned artichokes packed in water rather than heavily seasoned marinated artichokes.

Cream cheese: Full-fat cream cheese creates the richest, smoothest texture. Soften and cube it so it melts evenly.

Sour cream: Adds tanginess and helps balance the richness of the cheese.

Mayonnaise: Gives the dip a smooth, creamy consistency.

Mozzarella: Provides a mild flavour and stretchy melted-cheese texture.

Parmesan: Adds salty, savoury flavour. Freshly grated Parmesan melts more smoothly.

Milk: Loosens the dip. Add more only if the finished mixture is thicker than desired.

Garlic: Fresh garlic provides stronger flavour than garlic powder.

How to Drain Frozen Spinach Properly

Thaw the spinach completely.

Place it inside a clean kitchen towel, several layers of strong paper towel or a fine-mesh sieve.

Squeeze firmly until no more water comes out.

This is an important step. Excess spinach liquid can make the finished dip watery and dilute its flavour.

Ten ounces of frozen spinach will reduce to a much smaller quantity after draining.

How to Prepare Artichoke Hearts

Drain the artichoke hearts thoroughly.

Pat them dry with paper towel and chop them into small, bite-sized pieces.

Avoid leaving very large pieces, as these can make the dip difficult to scoop.

Check for any tough outer leaves and remove them before chopping.

How to Make Slow Cooker Spinach Artichoke Dip

Step 1: Prepare the Slow Cooker

Lightly grease the inside of a 3–4-quart slow cooker with cooking spray or a small amount of butter.

A smaller slow cooker helps prevent the dip from spreading into an excessively thin layer.

Step 2: Add the Creamy Ingredients

Add the cubed cream cheese, sour cream, mayonnaise and milk.

Distribute the cream cheese cubes evenly throughout the slow cooker.

Step 3: Add the Spinach and Artichokes

Add the thoroughly drained spinach and chopped artichoke hearts.

Break up any compact pieces of spinach so they distribute evenly.

Step 4: Add the Cheese and Seasonings

Add:

One cup of mozzarella.
Parmesan.
Minced garlic.
Onion powder.
Black pepper.
Optional red pepper flakes.

Reserve the remaining mozzarella for the top.

Stir the ingredients together as well as possible. The cream cheese will become easier to mix after warming.

Step 5: Slow Cook the Dip

Cover and cook on low for approximately 1½–2 hours.

Stir after the first hour, scraping around the edges and bottom.

Continue cooking until the cream cheese has melted and the mixture is thoroughly hot.

Slow cookers vary, so begin checking early to prevent the cheese from scorching around the sides.

Step 6: Add the Remaining Cheese

Stir the dip until creamy and evenly combined.

Sprinkle the reserved mozzarella over the surface.

Cover for another 10–15 minutes, until the cheese melts.

Step 7: Adjust the Consistency

If the dip is too thick, stir in warm milk one tablespoon at a time.

If it appears thin, leave the lid off and cook briefly while stirring frequently.

Taste and add salt only if required, as Parmesan and artichokes may already contain considerable salt.

Step 8: Garnish and Serve

Switch the slow cooker to its warm setting.

Garnish with chopped parsley, spring onion, red pepper flakes or additional Parmesan.

Serve warm with your preferred dippers.

Tips for Perfect Spinach Artichoke Dip

Remove as Much Water as Possible

Thoroughly draining the spinach and artichokes is the most important way to avoid watery dip.

Soften the Cream Cheese

Softened, cubed cream cheese melts more evenly and is easier to combine.

Grate the Cheese Freshly

Pre-grated cheese may contain anti-caking ingredients that affect smooth melting.

Use a Small Slow Cooker

A large slow cooker may spread the dip too thinly and cause the edges to cook too quickly.

Stir During Cooking

Stirring redistributes heat and prevents cheese from sticking around the sides.

Add Salt at the End

Several ingredients already contain salt. Taste the finished dip before seasoning further.

Avoid Overcooking

Extended cooking can make dairy-based dips oily or grainy.

What to Serve With Spinach Artichoke Dip

Serve it with:

Tortilla chips.
Pita chips.
Toasted baguette slices.
Crostini.
Crackers.
Pretzel crisps.
Breadsticks.
Carrot sticks.
Celery sticks.
Cucumber slices.
Sweet pepper strips.
Broccoli florets.

Use sturdy crackers and chips that will not break beneath the thick dip.

Oven-Baked Spinach Artichoke Dip

If you do not want to use a slow cooker:

Preheat the oven to 375°F.
Combine all ingredients, reserving some mozzarella.
Transfer the mixture to a greased baking dish.
Sprinkle the reserved cheese over the surface.
Bake until hot, bubbling and lightly golden.

Begin checking after approximately 20 minutes. Exact baking time will depend on the depth of the dish and starting temperature.

Spinach Artichoke Dip Variations

Spinach Artichoke Dip With Bacon

Fold cooked, crumbled bacon into the dip before serving.

Spicy Spinach Dip

Add chopped jalapeño, cayenne pepper or additional red pepper flakes.

Chicken Spinach Artichoke Dip

Add finely shredded cooked chicken for a heartier appetiser.

Four-Cheese Spinach Dip

Add grated cheddar or Monterey Jack alongside the mozzarella and Parmesan.

Garlic Parmesan Spinach Dip

Increase the garlic and add additional grated Parmesan.

Fresh Spinach Artichoke Dip

Cook approximately one pound of fresh spinach until wilted.

Allow it to cool, squeeze it thoroughly dry and chop it before adding it to the dip.

Lighter Spinach Artichoke Dip

Replace part of the mayonnaise and sour cream with plain Greek yoghurt. The flavour and texture will differ slightly.

Can You Make Spinach Artichoke Dip Ahead?

Yes. Combine all ingredients inside the removable slow-cooker insert or an airtight container.

Cover and refrigerate for up to 24 hours.

If the insert is ceramic, check the manufacturer’s instructions before moving it directly from the refrigerator into the heated slow-cooker base.

Alternatively, allow the ingredients to sit briefly while preparing the appliance.

A refrigerated mixture may require additional cooking time.

How Long Can You Keep the Dip Warm?

Once thoroughly heated, use the slow cooker’s warm setting for serving.

Stir the dip occasionally and keep the lid attached between servings.

Avoid leaving the dip out at room temperature for more than two hours.

If it becomes too thick, add a small amount of warm milk and stir well.

How to Store Leftovers

Allow the dip to cool slightly.

Transfer it to a shallow airtight container and refrigerate within two hours.

Use leftovers within 3–4 days.

Do not store the dip inside a warm slow-cooker insert for an extended period.

Can You Freeze Spinach Artichoke Dip?

Freezing is possible, but the dairy ingredients may separate or develop a grainy texture after thawing.

For the best result, prepare and serve the dip fresh.

If freezing is necessary, use an airtight freezer-safe container and freeze for up to one month. Thaw it overnight in the refrigerator and stir thoroughly while reheating.

How to Reheat Spinach Artichoke Dip

In the Slow Cooker

Return the dip to the slow cooker and heat on low, stirring occasionally.

In the Oven

Transfer it to a baking dish, cover and reheat at 350°F until thoroughly hot.

In the Microwave

Heat individual portions in short intervals, stirring between each interval.

Add a splash of milk if the dip becomes too thick.
