Great tostadas vary, but their composition—crispy base, creamy topping, substantial protein—is the same. Chef Daniela Soto-Innes thinks of these as a Mexican take on bagels with cream cheese and lox. The addictive caramelized fish sauce vinaigrette brightens every bite.

Salty-Sour Vinaigrette:
Step 1
Heat a small saucepan over medium. When hot, pour in 1 Tbsp. fish sauce. It should bubble up vigorously and then get thicker and slightly darker, about 30 seconds. Repeat with remaining fish sauce, incorporating 1 Tbsp. at a time. Carefully add vinegar (it may spatter), then transfer mixture to a small bowl; let cool. Stir in scallions and ginger. Taste and season with salt.
Tostadas:
Step 2
Preheat oven to 300°F. Mix lemon zest into cheese in a small bowl; season with salt and set aside. Place fish on a rimmed baking sheet and drizzle very lightly with oil; season with salt. Bake until just opaque throughout, about 5 minutes for char and 8–10 minutes for salmon. Remove from oven and break apart into large flakes. Drizzle with vinaigrette.
Step 3
Divide reserved cheese mixture among tostadas. Top with fish, then cilantro, chiles, and capers. Serve with lime wedges.
Do Ahead
Step 4
Vinaigrette can be made 1 week ahead. Cover and chill.

Back to TopSolid recipe. Sauce compliments the fish well. Perhaps my Arctic char fillet was a bit thick, but 300 degrees for five minutes was not nearly enough time. I believe the rule of thumb for cooking fish in the oven is 10 minutes for every inch of thickness at 400 degrees. I agree with the other reviewer that the recipe should be at least doubled for four servings.

Delicious! Really unique taste and a fun way to eat more fish. Used salmon and it turned out great. One caveat: a single tostada is a bit of a skimpy serving. Given that you're already buying more ricotta and tostadas than this calls for, just go ahead and double up on the fish if you're cooking for more than 2.

Delicious! Really unique taste. I'm trying to get the family to eat more seafood, and this was a different and un-fishy option. One caveat: a single tostada for a serving is pretty skimpy. Given that you're already buying at least four times this much ricotta and tostadas and the vinaigrette makes a ton, go ahead and double up on the salmon if you're feeding more than 2.
