Instructions

1. Brown the beef:

Preheat oven to 375°F (190°C).
In a large oven-safe skillet or Dutch oven, cook ground beef over medium-high heat 6–8 minutes, breaking into crumbles, until browned. Drain excess fat.

2. Sauté aromatics:

Add onion and bell pepper to skillet; cook 4–5 minutes until soft. Stir in garlic; cook 30 seconds more.

3. Make sloppy joe sauce:

Stir in tomato sauce, tomato paste, coconut aminos, sugar-free honey, vinegar, smoked paprika, garlic powder, onion powder, black pepper, salt, and optional red pepper flakes.
Simmer 3–4 minutes until slightly thickened and fragrant.

4. Add topping:

For drop biscuits: Mix almond flour, baking powder, salt, egg, melted butter, and Greek yogurt until a soft dough forms. Drop spoonfuls over filling.
For crumble: Mix breadcrumbs/pork rinds, melted butter, and seasoning; sprinkle evenly over filling.
For cheese-crisp: Mix cheeses + almond flour; sprinkle over filling.

5. Bake:

Cover with foil; bake 20 minutes.
Uncover; bake 10 more minutes until topping is golden and filling is bubbly.

6. Rest & serve:

Cool 5–10 minutes. Garnish with fresh parsley. Serve warm with optional pickles or jalapeños.

Slow Cooker Option (hands-off comfort!):
