6 large sea scallops (8 ounces total): The star of the show – sweet, delicate, and perfect for searing.

How to Make Seared Scallop Tostadas with Guacamole and Sour Cream Recipe

Step 1: Prepare the Guacamole Base

Start by mashing the ripe Haas avocado gently in a small bowl; you want it creamy but still a little chunky for texture. Stir in the diced tomato, red onion, cilantro, lime juice, kosher salt, and freshly ground black pepper. This guacamole is fresh and vibrant, providing the perfect balance of creaminess and bright, tangy notes that will anchor your tostadas beautifully.

Step 2: Season and Sear the Scallops

Pat your scallops dry to ensure a golden crust and season both sides with kosher salt and black pepper. Heat a 12-inch skillet over high heat and add butter and olive oil. When the butter just starts to smoke, carefully place the scallops in the pan, making sure they don’t touch. Sear them for exactly 1 and a half minutes on each side to achieve a gorgeous caramelized crust while keeping the center delightfully tender and translucent. This technique is the heart of the Seared Scallop Tostadas with Guacamole and Sour Cream Recipe — the scallops’ rich flavor and delicate texture need this precise sear to truly shine.

Step 3: Assemble the Tostadas

Spoon a generous layer of your fresh guacamole onto each crispy tostada shell. Arrange the perfectly seared scallops on top with care, then drizzle the thinned sour cream evenly over everything. This final touch brings a cooling creaminess that rounds out the tart lime and savory scallops, making each bite absolutely irresistible.

Garnishes

Adding a sprinkle of extra chopped cilantro, a little thinly sliced radish for crunch, or a handful of finely chopped green onions makes these tostadas pop visually and flavor-wise. A small wedge of lime on the side invites your guests to add a final tangy squeeze, truly elevating the experience.

Side Dishes

Pair these tostadas with a light side such as a crisp Mexican street corn salad or a refreshing jicama slaw. These sides complement the rich scallops and creamy guacamole without overwhelming the palate, creating a well-rounded meal.

Creative Ways to Present

For a fun twist, try serving the components in a build-your-own tostada style, letting everyone create their masterpiece. Or plate them elegantly with a drizzle of chipotle sauce on the side for a subtle smoky kick. Either way, these tostadas are a guaranteed crowd-pleaser.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftovers, store the guacamole separately in an airtight container with plastic wrap pressed directly on its surface to prevent browning. Keep scallops refrigerated in a sealed container and consume within one day for best flavor and safety.

Freezing

Because scallops are delicate, it’s best not to freeze cooked scallops or the assembled tostadas. However, you can freeze uncooked scallops properly sealed, then thaw and prepare fresh when ready.

Reheating

Reheat scallops gently in a warm skillet for about a minute per side, being careful not to overcook. Avoid reheating assembled tostadas to keep the shells crispy and the guacamole fresh.

FAQs

Can I use frozen scallops for this recipe?

Yes, frozen scallops are a convenient option. Just be sure to thaw them completely and pat dry to achieve that perfect sear essential in the Seared Scallop Tostadas with Guacamole and Sour Cream Recipe.

Is there a substitute for sour cream?

You can substitute Greek yogurt for sour cream if you prefer a slightly tangier and thicker texture, which also works wonderfully with the creamy guacamole and tender scallops.

How can I make this recipe gluten-free?

Simply choose corn tostada shells that are certified gluten-free to keep this dish safe for gluten-sensitive diners without sacrificing crunch or flavor.

What if I don’t like cilantro?

No worries! You can omit the cilantro or replace it with fresh parsley or basil for a different but equally delicious herbal note.

Can I prepare any parts of this dish ahead of time?

The guacamole can be made a few hours ahead and stored properly, but it’s best to sear scallops fresh to maintain their texture and flavor in your Seared Scallop Tostadas with Guacamole and Sour Cream Recipe.
