Ingredients

  

• 1.5 pounds ground beef (80/20 or 85/15)
• 1 tablespoon avocado oil or olive oil
• 1 medium yellow onion, thinly sliced
• 1 red bell pepper, thinly sliced
• 1 green bell pepper, thinly sliced
• 3 cloves garlic, minced
• 1 (14.5-ounce) can diced tomatoes, drained
• 2 tablespoons tomato paste
• 2 tablespoons butter
• 2 tablespoons chopped fresh parsley (optional)
• 1–2 teaspoons hot sauce (optional)
• 2 teaspoons smoked paprika (or sweet paprika if preferred)
• 1.5 teaspoons garlic powder
• 1.5 teaspoons onion powder
• 1 teaspoon dried oregano
• 1 teaspoon dried thyme
• 1 teaspoon kosher salt (more to taste)
• 1/2 teaspoon black pepper
• 1/4–1/2 teaspoon cayenne pepper (adjust to heat preference)
• Cauliflower rice or sautéed shredded cabbage
• Avocado slices or a dollop of sour cream
• Lemon wedges for a quick squeeze of acidity

Method

 

1. Mix the Cajun spices. In a small bowl, combine paprika, garlic powder, onion powder, oregano, thyme, salt, black pepper, and cayenne. Set aside.
2. Brown the beef. Heat the oil in a large skillet over medium-high heat. Add the ground beef and cook, breaking it up with a spatula, until browned and slightly crispy in spots, about 6–8 minutes. Spoon off excess fat if needed, leaving about 1–2 tablespoons in the pan.
3. Season the meat. Sprinkle half of the Cajun spice blend over the beef and stir well. Cook 1 minute to bloom the spices.
4. Soften the veggies. Add the onion and bell peppers. Cook, stirring occasionally, until softened and lightly charred at the edges, 6–8 minutes.
5. Add aromatics and tomato base. Stir in the garlic and cook until fragrant, 30 seconds. Add the drained diced tomatoes and tomato paste. Sprinkle in the remaining Cajun spice blend and stir to combine.
6. Simmer and reduce. Lower heat to medium. Let the mixture simmer 5–7 minutes, stirring occasionally, until thickened and glossy. If using hot sauce, add it now.
7. Finish with butter. Stir in the butter until melted. Taste and adjust salt, pepper, and cayenne if needed.
8. Garnish and serve. Remove from heat. Top with parsley. Serve over cauliflower rice or with your favorite keto sides. Add avocado or sour cream if you like a cooling element.

Keeping It Fresh

• Storage: Cool completely, then refrigerate in an airtight container for up to 4 days.
• Freezing: Portion into freezer-safe containers and freeze for up to 3 months.

  Thaw overnight in the fridge before reheating.

• Reheating: Warm on the stovetop over medium heat with a splash of water or broth. Microwave in short bursts, stirring between rounds.
• Make-ahead tip: Mix the Cajun spice blend in bulk and store it in a jar. It speeds up prep and works on chicken, shrimp, or roasted veggies too.

Benefits of This Recipe

• Keto-friendly: Low in carbs and free of grains, it supports a ketogenic eating style without feeling restrictive.
• High in protein: Ground beef delivers steady energy and satiety.
• Rich in flavor, not in fuss: Pantry spices create depth without complicated techniques.
• Budget-wise: Uses accessible ingredients and stretches well with low-cost sides like cauliflower rice.
• Customizable: Easily adjust heat, swap proteins, or tweak vegetables to fit your preferences.

Common Mistakes to Avoid

• Overcrowding the pan: If your skillet is small, brown beef in two batches so it sears instead of steams.
• Skipping spice blooming: Stir the spices into hot fat for a minute.

  It wakes them up and boosts flavor.

• Watery skillet: Drain the tomatoes and let the mixture simmer uncovered to thicken. Too much liquid will dull the seasoning.
• Under-salting: Taste at the end and season as needed. The right salt level makes the spices pop.
• Cranking the heat too high: After browning, reduce heat to avoid scorching the tomato paste or burning the garlic.

Recipe Variations

• Turkey or chicken: Swap in ground turkey or chicken.

  Add 1 extra tablespoon of oil to prevent dryness and consider a splash of chicken broth while simmering.

• Andouille accent: Add 4–6 ounces sliced andouille sausage with the onions and peppers for a smoky kick.
• Extra veg: Fold in chopped zucchini or riced cauliflower during the simmer step for more volume with few carbs.
• Creamy version: Stir in 2–3 tablespoons heavy cream or a spoonful of cream cheese at the end for a richer, silkier sauce.
• Cheesy top: Sprinkle shredded cheddar or pepper jack over the skillet, cover for 2 minutes, and let it melt.
• Spice swap: Use blackened seasoning or add a pinch of celery seed for a different Cajun-style profile.
