Taco night is an easy dinner staple in our house, and I have a feeling it’s the same in yours! But instead of just browning some ground beef and calling it a day, I want to show you how to make beef tacos that are truly loaded. Loaded with what? Well, with vegetables, fiber, and so much flavor. Trust me, once you make tacos this way, you’ll never go back.

Here’s the thing: adding zucchini, bell pepper, and black beans to your taco meat is one of the smartest and easiest ways to sneak more nutrients and fiber into a meal your family already loves. Nobody’s complaining. Nobody’s picking out the vegetables. (Just dice them small enough!) It all comes together in one skillet, and the whole thing is on the table in about 30 minutes. This is healthy eating that actually works in real life.

Why You’ll Love These Loaded Beef Tacos

One skillet, minimal cleanup. Everything cooks together, which means less time washing dishes and more time enjoying dinner with your family.
Sneaky vegetables your kids won’t notice. The zucchini, onion, and bell pepper are diced small enough that the blend into the beef mixture. It’s an easy way to get more vegetables into everyone in your family. I know sometimes it’s the adults who need this as much as the kids!
Packed with protein and fiber. Between the ground beef and the black beans, these tacos keep everyone full and satisfied long after dinner.
Endlessly customizable. Hard shells, soft shells, toppings galore—everyone at the table gets exactly what they want.
Budget-friendly. Stretching two pounds of beef with beans and vegetables means you’re feeding more people for less money. Win-win.

Loaded Beef Tacos Ingredients

Here’s everything you need to make these beef tacos shine:

1 zucchini, small diced – Zucchini is a nutritional powerhouse that often gets overlooked. It’s low in calories and rich in vitamin C, vitamin B6, potassium, and fiber. Dicing it small here means it blends seamlessly into the beef mixture—great for picky eaters!
1 red bell pepper, small diced – Red bell peppers are one of the best sources of vitamin C you’ll find—even more than oranges! They also provide a good dose of vitamin A and antioxidants that support immune health.
1 onion, small diced – Beyond adding incredible savory depth to the beef mixture, onions are loaded with antioxidants and compounds that support heart health and help reduce inflammation.
1 tablespoon avocado oil – Avocado oil has a high smoke point, making it ideal for sautéing vegetables at medium heat without oxidizing. It’s also rich in heart-healthy monounsaturated fats.
Salt and pepper – Simple seasoning that helps draw out the natural flavors of the vegetables as they cook.
2 pounds ground beef – The hearty, protein-rich base of these tacos. Look for a quality grass-fed ground beef when possible—it has a better nutritional profile, including more omega-3 fatty acids, compared to conventionally raised beef.
1/4 cup taco seasoning – I use my homemade taco seasoning here, and I cannot recommend it enough! Store-bought versions are often loaded with sodium, anti-caking agents, and additives you just don’t need. My version tastes better, and you know exactly what’s in it. Plus the flavor profile is my favorite of any taco seasoning I’ve tried.
1 (15 oz) can black beans, drained and rinsed – Black beans are one of the best things you can add to beef tacos. They’re a fantastic source of plant-based protein, fiber, folate, and iron. Adding them to the meat mixture is a simple way to boost nutrition and make the meal go further.
1 (15 oz) can fire roasted diced tomatoes (with juice) – Fire roasted tomatoes add a deeper, slightly smoky flavor that takes this taco meat to the next level. Tomatoes are also rich in lycopene, a powerful antioxidant linked to reduced risk of heart disease and certain cancers.
1/2 cup water – This helps the taco seasoning and tomatoes come together into a saucy, flavorful mixture that coats everything perfectly.

How to Make Loaded Beef Tacos

Printable instructions with ingredient quantities are available in the recipe card at the bottom of this post.

Finely dice your vegetables. Having the vegetables finely diced is key in having them accepted by picky family members. 😉 I use this vegetable chopper and it makes dicing the vegetables so fast and they are all small and uniform.
Sauté your vegetables. Heat the avocado oil in a large skillet over medium heat. Add the diced zucchini, red bell pepper, and onion, and season with salt and pepper. Cook, stirring occasionally, until the vegetables are softened—about 5 minutes.
Brown the beef. Add the ground beef to the skillet. Use a wooden spoon or spatula to break it apart and cook until it’s fully browned throughout. Drain any excess liquid from the pan.
Build the flavor. Add the taco seasoning, drained black beans, fire roasted diced tomatoes with their juice, and water. Stir everything together until well combined.
Simmer. Bring the mixture to a simmer, then cover and let it cook for 10–15 minutes. This step lets all those flavors meld together beautifully—don’t skip it!
Serve it up! Spoon the beef mixture into hard or soft taco shells and top with whatever your heart desires. See my topping suggestions below!

What to Serve With Loaded Beef Tacos

The beauty of these beef tacos is that the toppings are half the fun! Set up a little taco bar and let everyone build their own. Here are some ideas:

Toppings to pile on:

Shredded cheese
Sour cream or plain Greek yogurt (a great high-protein swap!)
Fresh restaurant style salsa or pico de gallo
Sliced avocado or guacamole
Shredded lettuce or cabbage
Fresh cilantro and a squeeze of lime
Pickled jalapeños

Side dishes to round out the meal:

Cilantro Lime Rice (you could also make this a taco bowl and not use shells at all)
Bean Salad
Tortilla chips with salsa or simple guacamole

FAQs

Can I use a different protein? Absolutely! Ground turkey or ground chicken work great in this recipe. The cooking method stays exactly the same.

Can I make this ahead of time? Yes! The beef taco mixture actually gets even better as it sits and the flavors deepen. Make it up to 3 days ahead and store it in an airtight container in the refrigerator. Reheat in a skillet over medium heat or in the microwave. This would also be really good as the protein for a taco bowl served with Cilantro Lime Rice.

Can I freeze the beef mixture? You can! Let it cool completely, then store in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator and reheat before serving.

Can I make this dairy-free? The beef mixture itself is completely dairy-free—just choose dairy-free toppings and you’re good to go.

What if my kids don’t eat vegetables? Dice them as small as possible! When the zucchini and pepper are cut small and cooked down, they become almost invisible in the meat mixture. You can also run the cooked vegetables through a quick pulse in a food processor before adding the beef if you have very determined veggie-avoiders at your table.
