Ingredients

Corn Tortillas: The foundation of our tostadas, providing a crispy and slightly nutty base. Look for sturdy tortillas that will hold up well when baked or fried.
Sweet Potatoes: The star of the show! These bring a natural sweetness and creamy texture to the tostadas. Choose medium-sized sweet potatoes for even roasting.
Black Beans: Packed with protein and fiber, black beans add a hearty and earthy flavor that perfectly complements the sweetness of the potatoes. Canned or cooked from dry both work well.
Olive Oil: Used for roasting the sweet potatoes and brushing the tortillas, olive oil adds healthy fats and enhances flavor. Extra virgin olive oil is recommended for its richer taste.
Chili Powder: Provides a warm, smoky depth of flavor and a touch of spice. Adjust the amount to your preferred heat level.
Cumin: Earthy and warm, cumin adds a classic Southwestern flavor that pairs beautifully with sweet potatoes and black beans.
Smoked Paprika: Adds a smoky and slightly sweet note that enhances the overall flavor profile and adds a layer of complexity.
Garlic Powder: Provides a savory and aromatic base flavor that ties all the ingredients together.
Onion Powder: Adds a subtle sweetness and savory depth, complementing the garlic powder and other spices.
Salt: Essential for enhancing the flavors of all the ingredients. Use kosher salt or sea salt for best results.
Black Pepper: Adds a touch of spice and complexity to the seasoning blend. Freshly ground black pepper is always preferred.
Lime Juice: Freshly squeezed lime juice adds a bright, acidic tang that balances the richness of the sweet potatoes and beans and brightens up the overall flavor.
Optional Toppings: This is where you can get creative! Consider options like shredded lettuce, diced tomatoes, avocado or guacamole, salsa, sour cream or Greek yogurt, shredded cheese (cheddar, Monterey Jack, or cotija), pickled onions, cilantro, jalapeños, or hot sauce.

Instructions

Preheat your oven to 400°F (200°C). This temperature is ideal for roasting the sweet potatoes to tender perfection and crisping up the tortillas.
Prepare the sweet potatoes: Wash and peel the sweet potatoes. Dice them into ½-inch cubes. Smaller cubes will roast faster and more evenly.
Season the sweet potatoes: In a large bowl, toss the diced sweet potatoes with 1 tablespoon of olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and black pepper. Ensure the sweet potatoes are evenly coated with the spices for maximum flavor.
Roast the sweet potatoes: Spread the seasoned sweet potatoes in a single layer on a baking sheet. Avoid overcrowding the pan, as this can cause them to steam instead of roast. Roast for 20-25 minutes, or until tender and slightly caramelized, flipping halfway through. The sweet potatoes should be easily pierced with a fork when done.
Prepare the black beans: While the sweet potatoes are roasting, rinse and drain the black beans if using canned beans. If using cooked black beans from dry, ensure they are cooked until tender but not mushy. You can gently warm the black beans in a saucepan on the stovetop if desired, or simply use them at room temperature.
Prepare the tortillas: Lightly brush both sides of the corn tortillas with olive oil. This will help them crisp up beautifully in the oven.
Bake the tortillas: Arrange the oiled tortillas in a single layer on a separate baking sheet. Bake in the preheated oven for 5-7 minutes, or until crispy and lightly golden brown. Keep a close eye on them to prevent burning, as baking times can vary. Alternatively, you can broil them for a minute or two per side for quicker crisping, but watch them very carefully. Another method is to lightly fry them in a skillet with a bit of oil until crispy.
Assemble the tostadas: Once the sweet potatoes and tortillas are ready, it’s time to assemble! Place a crispy tortilla on a plate.
Layer with black beans: Spoon a generous amount of black beans onto the crispy tortilla, spreading them evenly.
Top with roasted sweet potatoes: Layer the roasted sweet potatoes over the black beans.
Add toppings: Now comes the fun part! Top your tostadas with your favorite toppings. Some suggestions include shredded lettuce, diced tomatoes, avocado or guacamole, salsa, sour cream or Greek yogurt, shredded cheese, pickled onions, cilantro, jalapeños, and hot sauce. Get creative and customize your tostadas to your liking!
Serve immediately: Sweet Potato and Black Bean Tostadas are best enjoyed immediately while the tortillas are still crispy and the sweet potatoes are warm. Enjoy!

How to Serve

Sweet Potato and Black Bean Tostadas are incredibly versatile and can be served in various ways. Here are some ideas to elevate your tostada experience:

As a Main Course: These tostadas are hearty enough to be a satisfying main course, especially when loaded with toppings. Serve 1-2 tostadas per person for a complete and balanced meal.

This is a fun and interactive way to serve tostadas for parties or gatherings. Let everyone customize their own creations!
With a Side Salad: Pair the tostadas with a fresh and vibrant side salad to add extra vegetables and lightness to the meal. A simple green salad with a lime vinaigrette or a Mexican-inspired corn and black bean salad would be excellent choices.
With Spanish Rice or Quinoa: For a more substantial and complete meal, serve the tostadas alongside Spanish rice or quinoa. These grains add extra carbohydrates and fiber, making the meal even more filling.
As an Appetizer: Cut the tortillas into smaller rounds before baking to create mini tostadas that are perfect as appetizers for parties or gatherings. Offer a variety of toppings for guests to choose from.
Warm or Cold: While best enjoyed warm with crispy tortillas, the sweet potato and black bean mixture can also be prepared ahead of time and served cold or at room temperature on crispy tortillas for a quick and easy lunch or snack.
Garnished with Fresh Herbs: Garnish your finished tostadas with fresh herbs like cilantro, parsley, or even a sprinkle of chopped green onions for added freshness and visual appeal.
With a Dollop of Creamy Sauce: A dollop of creamy cilantro-lime sauce, chipotle crema, or avocado crema can add a delicious finishing touch to your tostadas and enhance the overall flavor profile.

Additional Tips for Perfect Sweet Potato and Black Bean Tostadas

Don’t Overcrowd the Baking Sheet: When roasting the sweet potatoes and baking the tortillas, make sure to spread them in a single layer on the baking sheet. Overcrowding will cause them to steam instead of roast or crisp, resulting in less desirable textures. Use two baking sheets if necessary or roast/bake in batches.
Adjust Spice Level to Your Preference: This recipe is moderately spiced. If you prefer a milder flavor, reduce the amount of chili powder and smoked paprika. For extra heat, add a pinch of cayenne pepper to the sweet potato seasoning or include diced jalapeños as a topping. You can also serve with hot sauce on the side.
Get Creative with Toppings: The toppings are where you can really customize your tostadas! Don’t be afraid to experiment with different combinations of fresh vegetables, salsas, cheeses, and creamy sauces. Consider adding roasted corn, pickled red onions, crumbled cotija cheese, or a drizzle of chipotle mayo.
Make it Vegan: This recipe is easily adaptable to be vegan. Simply ensure you use plant-based toppings like avocado, salsa, vegan sour cream, and skip the cheese or use a vegan cheese alternative.
Make it Gluten-Free: Corn tortillas are naturally gluten-free, making this recipe naturally gluten-free as well. Double-check the labels on your spices and toppings to ensure they are also gluten-free if needed.
Prepare Components Ahead of Time: You can save time by preparing the sweet potatoes and black beans ahead of time. Roast the sweet potatoes and cook the black beans (if using dry beans) a day or two in advance and store them in the refrigerator. This will make assembly much faster on a busy weeknight.
Crisp Tortillas in Different Ways: While baking is a healthy and easy way to crisp tortillas, you can also fry them in a shallow pan with a bit of oil for a more authentic crispy texture. Alternatively, you can use a dry skillet over medium heat to crisp them up quickly – just watch them closely to prevent burning. Broiling is another fast method, but requires careful monitoring.
Warm the Black Beans for Enhanced Flavor: While not strictly necessary, gently warming the black beans in a saucepan on the stovetop with a little water or broth can enhance their flavor and texture, especially if using canned beans. You can also add a pinch of cumin or chili powder to the beans while warming them for extra flavor.

FAQ Section

Q1: Can I make these tostadas ahead of time?

A: It’s best to assemble and serve tostadas immediately to maintain the crispiness of the tortillas. However, you can prepare the roasted sweet potatoes and black bean mixture ahead of time and store them separately in the refrigerator for up to 3 days. When ready to serve, crisp the tortillas and assemble the tostadas.

Q2: Can I use flour tortillas instead of corn tortillas?

A: While corn tortillas are traditional for tostadas and provide a more authentic flavor and texture, you can use flour tortillas if you prefer. Flour tortillas will crisp up slightly differently and will be a bit softer than corn tortillas. Make sure to use sturdy flour tortillas that will hold up to the toppings.

Q3: How can I make these tostadas spicier?

A: To increase the spice level, you can add a pinch of cayenne pepper to the sweet potato seasoning, include diced jalapeños or serrano peppers with the sweet potatoes while roasting, or add a dash of hot sauce to the black beans. You can also serve the tostadas with your favorite hot sauce on the side.

Q4: What are some good vegan toppings for these tostadas?

A: There are tons of delicious vegan toppings! Some great options include: avocado or guacamole, various salsas (pico de gallo, corn salsa, black bean salsa), shredded lettuce, diced tomatoes, pickled onions, cilantro, vegan sour cream or cashew cream, roasted corn, and black olives.

Q5: Can I freeze the leftover sweet potato and black bean mixture?

A: Yes, the sweet potato and black bean mixture freezes well. Let it cool completely, then transfer it to an airtight container or freezer bag and freeze for up to 3 months. Thaw overnight in the refrigerator or gently reheat on the stovetop or in the microwave until warmed through before assembling your tostadas.

Q6: What if I don’t have smoked paprika? Can I substitute it?

A: Smoked paprika adds a unique smoky flavor, but if you don’t have it, you can substitute regular paprika or omit it altogether. The flavor will be slightly different, but still delicious. You could also add a tiny pinch of liquid smoke (use sparingly!) to mimic the smoky flavor.

Q7: Can I bake or broil the tortillas without oil?

A: While brushing the tortillas with olive oil helps them crisp up and brown nicely, you can bake or broil them without oil for a slightly healthier option. They may not get as crispy and golden brown, but they will still become firm enough to use as tostadas. Watch them closely to prevent burning.

Q8: Can I use different types of beans instead of black beans?

A: Yes! While black beans are classic and work wonderfully, you can experiment with other types of beans. Pinto beans, kidney beans, or even chickpeas would be delicious alternatives. Adjust the seasoning as needed to complement the flavor of the beans you choose. For example, pinto beans might pair well with a bit more cumin, while chickpeas could benefit from a touch of curry powder.
