Instructions

  1. Step 1: For the tomato sauce, roughly chop 3 medium ripe tomatoes, 1 small white onion, and 1 garlic clove. Heat 2 tbsp vegetable oil in a saucepan over medium heat.
  2. Step 2: Add the chopped onion and garlic to the pan and sauté for 3 minutes until fragrant and translucent.
  3. Step 3: Add the chopped tomatoes to the pan along with 1/2 tsp salt and 1/4 tsp ground black pepper; simmer for 15 minutes, stirring occasionally, until the sauce thickens and brightens in color.
  4. Step 4: While the sauce simmers, mash 2 medium ripe avocados in a bowl with 2 tbsp lime juice, 1/2 tsp salt, and 2 tbsp chopped fresh cilantro until creamy but still chunky.
  5. Step 5: Warm 1 1/2 cups cooked black beans in a small saucepan over low heat, mashing slightly and seasoning with 1/2 tsp salt.
  6. Step 6: To assemble, spread a spoonful of the warm black beans onto each of the 6 corn tostadas, top with 2-3 tbsp of the tomato sauce, and finish with a generous dollop of guacamole.
  7. Step 7: Garnish with extra cilantro leaves if desired and serve immediately.

Frequently asked questions

How long does Tostadas with Tomato Sauce, Guacamole, and Black Beans take to make?

Total time is about 35 minutes (15 min prep + 20 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Tostadas with Tomato Sauce, Guacamole, and Black Beans?

Store in an airtight container at room temperature for crisp items, or in the fridge for anything dairy- or produce-based, for up to 3–5 days. Re-crisp baked snacks in a 300°F oven for 5 minutes if they soften.

Can I substitute ingredients in Tostadas with Tomato Sauce, Guacamole, and Black Beans?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Tostadas with Tomato Sauce, Guacamole, and Black Beans for a different number of people?

The recipe is written for 6 servings. Multiply each ingredient by (your serving target / 6). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

What goes well with Tostadas with Tomato Sauce, Guacamole, and Black Beans?

Latin American snacks like this pair well with a simple grain (rice, couscous, or crusty bread), a quick salad with acid (lemon vinaigrette, pickled onions), and a pan sauce or yogurt-based dip. Tap "Plan a meal with the AI" to get specific side suggestions.
