Seven-layer dip is refried beans, sour cream, guacamole, salsa, shredded cheese, tomatoes and scallions or olives, spread in that order in a shallow dish so every chip goes through all of them. You can build the bottom layers the night before. The guacamole and the fresh toppings go on within a few hours of serving, because they are the parts that brown, weep or wilt.
It is a dip that rewards planning more than skill. The work is in getting each layer ready and in knowing which ones can wait.
The seven layers, bottom to top
There is no official recipe, and many families use eight or nine layers. The classic version, built from the bottom up:
- Refried beans, seasoned with taco seasoning or cumin and chili powder, and loosened with a little salsa so they spread.
- Sour cream, sometimes mixed with cream cheese for body.
- Guacamole, or mashed avocado with lime and salt.
- Salsa, drained.
- Shredded cheese, cheddar or a Mexican blend.
- Diced tomatoes.
- Sliced scallions or black olives, or both.
The order is not arbitrary. Beans on the bottom give the chip a firm base to scoop against. Sour cream sits between beans and guacamole as a seal. Cheese over the salsa catches any moisture before it reaches the toppings.
Choose the dish
A clear glass dish shows off the stripes, which is half the appeal. Shallow and wide is better than deep and narrow: an 8-by-8-inch or 9-by-13-inch baking dish, about two inches deep, lets every chip reach the bottom without breaking. A pie plate works for a smaller crowd.
A 9-by-13 dish serves 15 to 20 people as part of a spread.
The night before: the base
These layers keep well, covered, in the refrigerator for a day.
Beans. Warm one or two cans of refried beans with a teaspoon of cumin, a teaspoon of chili powder and a few spoonfuls of salsa, until spreadable. Cool them before spreading, so they do not melt the sour cream.
Sour cream. Stir in a squeeze of lime and a pinch of salt. For a sturdier layer, beat it with an equal amount of softened cream cheese.
Spread the beans in the dish, then the sour cream, smoothing each to the edges with an offset spatula. Spreading all the way to the glass seals each layer and makes clean stripes. Cover the dish tightly and refrigerate.
Cheese. Shred it now. Block cheese shredded at home melts into the dip better and tastes sharper than pre-shredded, which is coated in anti-caking agents. Store it in a bag.
On the board: the toppings
The toppings are where the knife does the work, and they are small cuts.
Tomatoes. Use plum or Roma tomatoes; they are firmer and less watery. Quarter them lengthwise and run the knife along the inside to remove the seeds and pulp. Dice the walls into quarter-inch pieces. Salt them lightly in a sieve and let them drain for 15 minutes, which keeps juice from pooling on the dip.
Scallions. Trim the roots and the dry tips. Slice the white and pale green parts into thin rounds, and the dark green tops on a slight bias for color.
Black olives. Buy them whole and pitted, drain them, and slice into rings. They are firmer and have more flavor than pre-sliced.
Cilantro and jalapeño, if you are adding them, chopped fine.
You can cut the scallions and olives the morning of the game and keep them covered. Cut the tomatoes no more than four hours ahead.
Within a few hours of serving
Guacamole. Make it last, from three or four ripe avocados mashed with lime, salt and a little minced onion. The safe way to halve and pit them is in how to cut an avocado safely. Spread it right over the sour cream, all the way to the edges.
Salsa. Drain it in a sieve for ten minutes first. Watery salsa is the most common reason a seven-layer dip turns soupy.
Then the cheese, then the tomatoes, then the scallions and olives in stripes or scattered. Cover the dish with plastic wrap, pressing it lightly onto the top layer, and refrigerate until kickoff.
Recipes put the fully assembled dip anywhere from six hours to a day ahead; six hours is the safe end, and the base layers alone keep for a day. With sour cream and cheese in it, do not leave it at room temperature for more than two hours. For a long game, set out half and keep the rest cold.
Variations worth trying
The seven layers are a template, not a rule. A few swaps that hold up well:
- Black beans mashed with garlic and lime instead of refried beans, for a lighter, smokier base.
- Greek yogurt in place of half the sour cream, for tang.
- Seasoned ground beef or chorizo, cooked, drained and cooled, as an extra layer above the beans for a heartier dip.
- Pickled jalapeños, chopped, scattered with the scallions for heat.
- Cotija crumbled over the top instead of cheddar, for salt and a drier finish that never turns greasy.
Whatever you change, keep the logic: firm and rich at the bottom, wet in the middle and sealed under cheese, fresh and crisp on top.
Serving it
Set the dish out with sturdy chips: thick tortilla chips or scoops, not thin restaurant-style chips, which snap against the beans. Put a spoon in one corner for people who want a scoop on their plate.
All the toppings come off one board in about fifteen minutes. The WONAMU. bamboo cutting board is 12 by 9 inches, enough to keep the tomatoes, scallions and olives in separate piles, and its juice groove catches the tomato liquid before it reaches the counter.
For the rest of the spread, the nacho board for game day uses many of the same toppings.
The short version
Layer beans, sour cream, guacamole, salsa, cheese, tomatoes and scallions or olives in a shallow glass dish. Build the beans and sour cream the night before and shred the cheese. Seed, dice and drain the tomatoes, slice the scallions and olives, and drain the salsa. Add the guacamole and toppings within six hours of serving, and keep the dip cold.
