The 6 Healthy Bento Box Recipes

Here are six full recipes to build your perfect meal prep lunch. The following recipes each make about 4 servings.

1. The Greek Chicken & Quinoa Box

The perfect balance of savory and fresh, this box is a high-protein classic — and if you fall in love with the grain base, our high-protein quinoa meal prep doubles the batch so you can roll the leftovers straight into tomorrow’s bento.

What You’ll Need:

  • 1 lb chicken breast, cut into 1-inch cubes
  • 2 tbsp olive oil
  • 1 tbsp lemon juice
  • 1 tsp dried oregano
  • 2 cloves garlic, minced
  • Salt and pepper to taste
  • 1 cup dry quinoa, rinsed
  • 2 cups water or gluten-free chicken broth
  • 1 English cucumber, diced
  • 1 cup cherry tomatoes, halved
  • 1/2 cup Kalamata olives
  • 1/2 cup hummus

How to Make It:

  1. Cook the Quinoa: Combine the rinsed quinoa and water or broth in a saucepan. Bring to a boil, then reduce heat, cover, and simmer for 15 minutes, or until the liquid is absorbed. Fluff with a fork and set aside to cool.
  2. Cook the Chicken: In a bowl, toss the chicken cubes with olive oil, lemon juice, oregano, minced garlic, salt, and pepper. Sauté in a hot skillet over medium-high heat for 5-7 minutes until golden brown and cooked through. Let cool.
  3. Assemble the Boxes: Divide the cooled quinoa among four bento boxes. Top with the cooled chicken. Add the diced cucumber, cherry tomatoes, and olives to a separate compartment. Place a scoop of hummus in a small, lidded container or a silicone cup.

2. The Deconstructed Burger Box

All the satisfaction of a juicy burger without the bun — and if you want to lean further into ground-beef comfort food this week, our homemade gluten-free Salisbury steak uses the same patty technique with a quick pan gravy.

What You’ll Need:

  • 1 lb lean ground turkey or beef
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • Salt and pepper to taste
  • 2 large sweet potatoes, cut into wedges
  • 1 tbsp olive oil
  • Toppings: Shredded lettuce, cherry tomatoes, dill pickle slices
  • For the Sauce: 1/4 cup mayonnaise, 1 tbsp ketchup, 1 tbsp pickle relish

How to Make It:

  1. Roast the Fries: Preheat your oven to 400°F (200°C). Toss the sweet potato wedges with olive oil, salt, and pepper. Roast on a baking sheet for 20-25 minutes, flipping halfway, until golden and tender. Let cool.
  2. Make the Patties: While the fries roast, combine the ground meat with garlic powder, onion powder, salt, and pepper. Form into 4 small patties. Cook in a skillet over medium heat for 4-5 minutes per side, or until cooked through. Let cool.
  3. Mix the Sauce: In a small bowl, whisk together the mayonnaise, ketchup, and pickle relish.
  4. Assemble the Boxes: Place a cooled burger patty in the main compartment of each box. Add the sweet potato fries and fresh toppings to separate sections. Portion the sauce into small, lidded containers.

3. The No-Cook Protein Bistro Box

The ultimate grab-and-go option for your busiest days—no cooking required! For more pairings to rotate into this compartment so you don’t get bored by Wednesday, steal from our high-protein snack ideas list.

What You’ll Need:

  • 8 hard-boiled eggs, peeled
  • 4 oz sharp cheddar cheese, cubed
  • 1 cup almonds or cashews
  • 1 box of your favorite gluten-free crackers
  • 1 cup red or green grapes
  • 2 celery stalks, cut into sticks
  • 1/2 cup almond butter

How to Make It:

  1. Prep: The only prep is to boil the eggs ahead of time.
  2. Assemble the Boxes: Artfully arrange the items in your bento boxes. Place 2 hard-boiled eggs, a handful of cheese cubes, nuts, and crackers in separate compartments. Add the grapes and celery sticks. Place the almond butter in a small, lidded container for dipping.

4. The Salmon & Asparagus Box

An elegant and nutrient-dense powerhouse lunch that cooks on one pan — the same hands-off technique we use for sheet pan teriyaki chicken and broccoli, so once you nail the timing, you’ve unlocked two weeks of bento bases.

What You’ll Need:

  • 4 (4-oz) salmon fillets
  • 1 lb asparagus, trimmed
  • 2 tbsp olive oil
  • 1 tsp garlic powder
  • Salt and pepper to taste
  • 1 cup dry wild rice mix
  • 4 lemon wedges for serving

How to Make It:

  1. Cook the Rice: Prepare the wild rice according to package directions. Let cool.
  2. Roast the Salmon & Asparagus: Preheat oven to 400°F (200°C). Place the salmon fillets and asparagus on a single baking sheet. Drizzle with olive oil and season with garlic powder, salt, and pepper. Roast for 12-15 minutes, until the salmon is flaky and the asparagus is tender-crisp. Let cool.
  3. Assemble the Boxes: Divide the cooled rice among the four boxes. Place a salmon fillet and a portion of the roasted asparagus alongside it. Add a fresh lemon wedge to each box for squeezing over the fish just before eating.

5. The DIY Taco Salad Box

A fun, deconstructed salad that stays fresh and crisp until lunchtime — season the meat with our homemade gluten-free taco seasoning so you skip the wheat-flour fillers hiding in most store-bought packets.

What You’ll Need:

  • 1 lb ground chicken or turkey
  • 1 packet gluten-free taco seasoning
  • 1 (15-oz) can black beans, rinsed and drained
  • 1 (15-oz) can corn, drained
  • 1/2 red onion, finely diced
  • 4 cups shredded romaine lettuce
  • For serving: Gluten-free tortilla chips, salsa, guacamole

How to Make It:

  1. Cook the Meat: In a skillet, brown the ground chicken. Drain any excess fat. Add the taco seasoning and a splash of water, simmering for 2-3 minutes until the sauce thickens. Let cool.
  2. Make the Salsa: In a bowl, combine the rinsed black beans, corn, and diced red onion.
  3. Assemble the Boxes: To keep things from getting soggy, assembly is key. Place the shredded lettuce in the largest compartment. Add a scoop of the cooled taco meat and a scoop of the corn and bean salsa in separate sections. Pack the tortilla chips, salsa, and guacamole in their own sealed compartments or containers.

6. The Shrimp & Avocado Box

A light, zesty, and refreshing meal that feels like a special treat — and if you love this layered, no-sog approach, our mason jar cobb salad meal prep uses the same compartmentalize-everything trick to keep avocado and dressing fresh for five days.

What You’ll Need:

  • 1 lb raw shrimp, peeled and deveined
  • 1 tbsp olive oil
  • 2 cloves garlic, minced
  • 1 cup dry long-grain white rice
  • 1/2 cup fresh cilantro, chopped
  • Juice of 1 lime, plus more for the avocado
  • 2 avocados
  • 1 cup cherry tomatoes, halved

How to Make It:

  1. Make the Rice: Cook the rice according to package directions. Once cooked and while still warm, fluff it with a fork and stir in the chopped cilantro and lime juice. Let cool completely.
  2. Cook the Shrimp: Heat olive oil in a skillet over medium-high heat. Add the minced garlic and cook for 30 seconds until fragrant. Add the shrimp and cook for 2-3 minutes, flipping once, until pink and opaque. Let cool.
  3. Assemble the Boxes: Divide the cooled cilantro-lime rice among the bento boxes. Top with the cooled shrimp. Add the cherry tomatoes to a side compartment. Just before sealing the box, slice the avocado, toss it with a little extra lime juice to prevent browning, and place it in its own compartment.

Strategic Meal Prep Tips

  • Cool Completely: Never pack warm food. Wait for all cooked components to cool to room temperature before sealing containers to prevent condensation and sogginess.
  • Dressings on the Side: Always pack dressings, sauces, and wet ingredients like guacamole or hummus in separate, leak-proof containers.
  • Batch Your Grains & Proteins: Cook all your rice, quinoa, and proteins at once to streamline the assembly process for the week.
