Spooky Halloween Seven Layer Taco Dip is a favorite at this Nest. This festive dip layers a bean spread, fresh guacamole, and a seasoned sour cream topping, then is finished with shredded cheddar, diced tomatoes, sliced black olive spiders, and chopped green onions.

Add a spooky sour cream spider web and olive spiders and you have a perfect Halloween party dip.

I made this for our family Halloween party last year and it quickly became a hit. The combination of layered flavors on a crisp corn chip delivers a mini tostada in every bite.

The recipe is a classic—often called Tex‑Mex dip years ago—but it’s now widely known as Seven Layer Dip. For this Halloween version, I add a spider web of sour cream and olive spiders for a fun presentation.

How To Make Seven Layer Spooky Spider Dip

Do as much prep as you can before assembling. Chop 1/2 cup green onions, halve, seed and coarsely chop about 1 cup tomatoes (roughly 1 large tomato), drain and slice one can of pitted olives and reserve six whole olives for the spiders. Grate 8 ounces cheddar cheese.

In the bottom of a 9‑inch deep dish pie plate, spread one can of plain or jalapeño bean dip evenly.

Next, peel, pit and mash two large ripe avocados in a bowl. Add 1 tablespoon lemon juice, 1/4 tsp garlic salt and 1/4 tsp coarse black pepper. Mix well to make guacamole.

Spread the guacamole over the bean dip, keeping chips away until assembly is complete.

In a small bowl, combine 1/2 cup mayonnaise, 1 cup sour cream and one package of taco seasoning. Stir until smooth.

Spread the sour cream mixture over the guacamole, making sure it reaches the edges to seal and help prevent the guacamole from browning.

Cover with 8 ounces of finely grated cheddar or a cheese blend.

For the Halloween look, arrange the tomatoes, sliced olives and chopped green onions around the outer edge of the dip instead of covering the whole top.

Sprinkle the sliced olives and chopped green onions next to the tomatoes.

To pipe a spider web, put 1/2 cup sour cream into a small sandwich bag, snip a tiny corner off and squeeze concentric circles or crossed lines across the cheese, then drag a toothpick from center to edge and between the circles to form a web.

Make olive spiders by cutting one olive lengthwise for the body, a small round slice for the head, and thin slices for legs. Arrange spiders on the web. (No need to be perfect—quirky spiders are part of the charm.)

Cover and chill until ready to serve. Offer round corn tortilla chips for scooping.

This dip makes a fun centerpiece for a Halloween spread and pairs nicely with other themed treats. It’s easy to assemble, visually festive, and full of familiar flavors that guests love. It can even be a satisfying snack on its own—guilty as charged!
