Follow these detailed steps carefully to ensure your Spinach Artichoke Dip Cups are perfectly crispy, creamy, and delicious every single time. The process is straightforward and rewarding.

Step 1: Prepare Your Oven and Muffin Tin
First things first, preheat your oven to 375°F (190°C). This ensures the wonton cups cook evenly and become perfectly crisp. Next, take a standard 12-cup muffin tin and lightly grease it with non-stick cooking spray or a light coating of olive oil. This is a vital step to prevent the wonton wrappers from sticking, ensuring they release easily once baked.

Step 2: Form the Wonton Cups
Gently press one wonton wrapper into each of the greased muffin cups. Use your fingers to press the wrapper down into the bottom and up the sides of the cup, creating a small, star-shaped vessel. You may see some of the corners overlap or stick up, which is perfectly fine—these will become the extra-crispy, golden-brown edges. Once all 12 cups are lined, place the muffin tin in the preheated oven and bake for 5-7 minutes. This pre-baking step is crucial; it helps the bottom of the wonton wrappers to set and begin crisping, which is the secret to avoiding a soggy bottom once the creamy filling is added. You’re looking for the wrappers to be lightly golden and firm.

Step 3: Prepare the Spinach and Artichokes
While the wonton cups are pre-baking, it’s time to prep your star ingredients. Your thawed frozen spinach must be thoroughly squeezed dry. You can do this by placing it in a clean kitchen towel or a few layers of heavy-duty paper towels and wringing it out over the sink until no more liquid comes out. You’ll be surprised how much water it holds! This step is non-negotiable for a creamy, not watery, dip. Next, drain your canned artichoke hearts very well and give them a rough chop. You want pieces that are small enough to be easily scooped in a single bite, but large enough to still provide a noticeable, tender texture.

Step 4: Mix the Creamy Filling
In a large mixing bowl, combine the softened cream cheese, sour cream, and mayonnaise. Using a hand mixer or a sturdy spatula, beat these ingredients together until they are completely smooth and well-incorporated. You don’t want any lumps of cream cheese remaining. Once the base is smooth, stir in the minced garlic, the thoroughly squeezed spinach, the chopped artichoke hearts, the grated Parmesan cheese, a half cup of the shredded mozzarella cheese (reserving the other half for the topping), the salt, and the black pepper. Mix everything together until it’s evenly distributed. Take a moment to taste the filling and adjust the seasoning if necessary.

Step 5: Fill and Top the Cups
Remove the pre-baked wonton cups from the oven. Carefully spoon the spinach and artichoke mixture evenly into each of the golden cups. Be generous, but try not to overfill them, as the filling will bubble and expand slightly as it bakes. A heaping tablespoon per cup is usually the perfect amount. Once all the cups are filled, sprinkle the remaining half cup of shredded mozzarella cheese over the top of each one. This will create that irresistible, bubbly, golden-brown cheese cap.

Step 6: Bake to Perfection
Place the filled muffin tin back into the 375°F (190°C) oven. Bake for an additional 12-15 minutes. You’ll know they are done when the filling is hot and bubbly and the cheese on top is melted and lightly golden. The edges of the wonton wrappers should be a deep, crispy golden brown. Keep a close eye on them during the last few minutes of baking to ensure the edges don’t burn.

Step 7: Cool and Serve
Once baked to perfection, carefully remove the muffin tin from the oven. Let the Spinach Artichoke Dip Cups cool in the tin for at least 5-10 minutes. This is an important step that allows the filling to set up slightly and the cups to firm up, making them much easier to remove without breaking. After they’ve cooled a bit, you can use a small offset spatula or a butter knife to gently lift them out. Arrange them on a platter and serve warm.
