Ingredients
- 1.5 lbs 80/20 Ground Beef
- 2 large Zucchinis, diced
- 1 Red Bell Pepper, chopped
- 1 Green Bell Pepper, chopped
- 1/2 Yellow Onion, finely diced
- 3 cloves Garlic, minced
- 2 tbsp Olive Oil
- 1 tsp Sea Salt
- 1/2 tsp Black Pepper
- 1 tbsp Chili Powder
- 1 tsp Cumin
- 1/2 tsp Smoked Paprika
- 1 cup Shredded Cheddar Cheese (optional)
- Fresh Cilantro for garnish
Directions
Step 1: Preparation
Start by washing all your fresh produce. Dice the zucchinis into bite-sized cubes and chop the bell peppers into uniform pieces. Finely mince the onion and garlic. Having everything chopped and ready to go makes the cooking process much faster. Set out four glass meal prep containers on your counter so you can divide the portions easily once the cooking is finished.
Step 2: Cooking the Beef and Vegetables
Heat a large skillet over medium-high heat. Add the ground beef and cook until fully browned, breaking it apart with a wooden spoon as it cooks. Once browned, drain the excess grease but leave about a tablespoon for flavor. Add the diced onions and bell peppers to the skillet with the beef. Sauté for about 5 minutes until the onions become translucent. Stir in the garlic, zucchini, and all the spices. Continue cooking for another 7-10 minutes until the zucchini is tender but still has a slight bite.
Step 3: Plating and Storage
Turn off the heat and give everything a final toss to ensure the spices are evenly distributed. Evenly divide the beef and vegetable mixture into your four meal prep containers. If you are using cheese, sprinkle it over the top while the mixture is still hot so it melts slightly. Allow the meals to cool to room temperature before snapping on the lids. Store them in the refrigerator for up to four days.
Expert Tips for Perfect Keto Meal Prep Beef Low Carb Under 20g Net Carbs Easy
To get the best results, avoid overcooking the zucchini. Zucchini has a high water content and can become mushy if cooked too long; aim for a “fork-tender” texture. If you want a deeper flavor, sear the beef without stirring for the first 3 minutes to get a nice brown crust. Always use glass storage containers if possible, as they reheat more evenly and don’t retain odors or stains like plastic ones. Finally, wait until the food is completely cool before sealing the lids to prevent steam from making the vegetables soggy.
Delicious Variations
You can easily swap the flavors in this dish to keep your meal plan exciting. For an Asian-inspired twist, swap the chili powder and cumin for ginger, soy sauce (or coconut aminos), and a drizzle of sesame oil. If you prefer more heat, add diced jalapeños or a dash of crushed red pepper flakes during the vegetable sauté. For extra healthy fats, serve each portion with half a fresh avocado or a dollop of full-fat sour cream right before eating. You can also swap the ground beef for ground turkey or bison depending on your preference.
