Healthy Sheet Pan Taco Dinner FAQs–What I learned while making this recipe.
How to make flavorful ground beef for tacos.
- Select 85/15 or 90/10 lean ground beef for maximum flavor and texture.
- For the best flavor, pan-sear the beef in a hot skillet. Add all the meat at once, pressing it lightly into the pan in one layer without breaking it up. Let it cook undisturbed for a few minutes, then flip it over, break it into chunks, and continue cooking until fully browned. This method creates a rich, caramelized crust that makes the filling extra savory and delicious.
- Add the cooked aromatics–onion, red pepper, and mushrooms–to the ground beef once you’ve pan-seared the beef.
- Add the taco seasoning the last few minutes of cooking the beef. The fat from the beef will ensure the seasoning is incorporated into the beef and aromatics.
Why add mushrooms to the ground beef?
A blend of finely chopped portobello mushrooms melts into the beef, enhancing the natural umami flavor while keeping the filling tender and juicy. No one will even notice they’re there. I promise!
Here are a few tips for using mushrooms with ground beef.
- Use portobello mushrooms for the most flavor. They are also slightly more nutrient dense and provide a “meatier” texture.
- Remove the stems by snapping or cutting them off. Use a teaspoon and scrape out the gills.
- Wipe the caps clean using a damp paper towel. If they are very dirty, give a quick rinse but wipe dry before using.
- Finely chop the mushrooms to the same size as ground beef crumbles.
- Caramelize in a hot pan with olive oil prior to adding the beef.
How to prepare and bake crispy corn tortillas without frying?
- Place five corn tortillas in a damp paper towel and microwave for 40 seconds. This will make them pliable so you can fold them. Through trial and error, there is a sweet spot when microwaving the tortillas. Not long enough and they will break.
- Place them on a lightly greased sheet pan, add fillings, fold over and brush with more olive oil. Adding cheese on top will also make them extra crispy and delicious.
- Bake at 400F for about 15 minutes.
- Place under the broiler for additional crispiness, but watch carefully.
Recipe Substitutions
- Can I substitute the ground beef? Yes! Ground chicken or turkey works well if you prefer a lighter option. Just keep in mind that the mushrooms pair best with beef, so the flavor will be most robust with the original recipe.
- Can I use flour tortillas? Yes, you can—but I recommend corn tortillas. They hold up better when baked and get perfectly crispy, plus they have a richer flavor and a bit more nutritional value than flour tortillas.

Ingredients
3/4 cup finely chopped red bell pepper (1 medium sized pepper)
3/4 cup yellow sweet onion, finely chopped
1-1/2 cups finely chopped portobello mushrooms (3-4 mushrooms)
2-3 Tablespoons olive oil, additional for brushing on corn tortillas
1 pound lean ground beef
2 Tablespoons taco seasoning (see recipe notes)
12 corn tortillas (5-1/2 inches)
2-3 cups shredded cheddar, pepper jack, or any Mexican melting cheese
- Avocado Lime Crema
1 avocado
1/4 cup plain Greek yogurt
Juice from 1 lime
1/4 cup cilantro leaves
1 garlic clove
1 teaspoon honey
pinch of salt and pepper
Directions
- Preheat a large frying pan to medium heat with 1 Tablespoon olive oil. Add in the 3/4 cup chopped red pepper and cook for 2 minutes, stirring occasionally. Add in 3/4 cup chopped onion and cook the pepper and onion for another 2 minutes, then add in 1-1/2 cups chopped mushrooms. Cook the mixture another 5 minutes until vegetables are caramelized. Add more olive oil if needed.
- Remove the vegetables from the pan and set aside. Place the ground beef in the pan in an even layer, pressing lightly to flatten. Allow to brown for about 4 minutes without disturbing, then flip over and break into chunks. Cook another 3 minutes, then stir in the cooked vegetables and add 2 Tablespoons of taco seasoning, cooking for another 1-2 minutes. Taste the mixture and add salt if needed. Remove from heat.
- Preheat oven to 400F. Prepare a large sheet pan with a very thin layer of olive oil or cooking spray.
- Wrap 5 tortillas at a time in a damp paper towel and heat in microwave for 40 seconds. Carefully remove from microwave. Remove one tortilla and cover the rest with the paper towel. Place the tortilla on the greased baking sheet and fill with 3 Tablespoons of beef mixture and about 2 Tablespoons of shredded cheese. Fold over. Repeat this process with the remaining tortillas.
- Brush the filled tortillas with olive oil or use vegetable spray (tip-sprinkle with taco seasoning if desired) and top with more cheese. Bake for 15 minutes until crispy. Optional–add more cheese on top of the tacos and broil on low for about 2 minutes, watching carefully.
- While the filled tortillas are baking, make the avocado crema. Add all the ingredients into a food processor or blender to combine. Place in a serving dish.
- Remove tacos from the oven and serve with avocado lime crema, lime wedges, and cilantro. Enjoy!
Notes
- For the taco seasoning, use a packaged mix or 2 Tablespoons of this taco seasoning recipe: 1 Tablespoon ground chili powder, 2 teaspoons of ground cumin, 1/2 teaspoon each: sweet paprika, granulated garlic and granulated onion; and 1/4 teaspoon each oregano, salt, and black pepper.
- I’ve found the sweet spot for warming corn tortillas is 40 seconds in the microwave, wrapped in a paper towel—this works well for 5 tortillas at a time. After filling those, microwave the next batch and repeat. Following this method helps prevent the tortillas from cracking, so your tacos stay soft and easy to fold.
- Leftovers? Store in a covered container for up to four days. To reheat, place on a sheet pan in a 350 degree preheated oven until heated through, about 15 minutes. Long term storage: freeze in an airtight plastic storage bag for up to 3 months. Bake frozen at 350F for about 20 minutes.
- To prepare in advance. Cook the vegetable and beef mixture up to two days before making this recipe. The avocado lime crema can be made a day in advance, though the color may change slightly to a darker green.
