  • Author: WAFA LI

Ingredients

Scale
(Serves 6–8)

Creamy chicken filling:

  • 2 lbs boneless, skinless chicken breasts or thighs, cubed (you love high-protein!)
  • 1 tbsp olive oil or avocado oil
  • 1 small onion, diced
  • 2 cups fresh broccoli florets or green beans (you love fresh produce!)
  • 46 garlic cloves, minced (you love garlic!)
  • 1 (8 oz) block full-fat cream cheese, softened (you love cream cheese—memory #11!)
  • 1 cup shredded reduced-sodium cheddar, Monterey Jack, or mozzarella (you love low-sodium!)
  • ½ cup low-sodium chicken broth (you love low-sodium!)
  • ½ cup heavy cream or full-fat coconut milk
  • 1 tsp dried Italian seasoning or thyme
  • ½ tsp black pepper
  • Salt to taste (use reduced-sodium—you love low-sodium!)
  • Optional: 6 slices bacon, cooked crisp and crumbled (you love bacon richness!)

Sugar-free “biscuit” topping (the bubble magic!):

  • 1½ cups almond flour (you love almond flour—memory #25!)
  • 2 tsp baking powder (aluminum-free)
  • ¼ tsp salt
  • 1 large egg, room temperature
  • 3 tbsp melted butter or coconut oil
  • 2 tbsp plain Greek yogurt or sour cream (adds fluffiness!)
  • Optional: 1 tbsp fresh herbs (parsley, chives)

Finish:

  • Extra shredded cheese for topping
  • Fresh parsley or chives
  • Lemon zest (brightens richness—you love citrus!)

Instructions

1. Prep filling:
Preheat oven to 375°F (190°C).
Heat oil in large oven-safe skillet or Dutch oven over medium-high heat. Add chicken; cook 5–6 minutes until golden. Remove; set aside.
2. Sauté aromatics & veggies:
In same skillet, add onion and broccoli/green beans; cook 4–5 minutes until crisp-tender. Stir in garlic; cook 30 seconds more.
3. Make creamy sauce:
Reduce heat to low. Add cream cheese, broth, and heavy cream; whisk until smooth.
Stir in ¾ cup shredded cheese, Italian seasoning, pepper, salt, and optional bacon until melted and glossy.
Return chicken to skillet; stir to coat.
4. Make biscuit topping:
In a bowl, whisk almond flour, baking powder, and salt.
Add egg, melted butter, and Greek yogurt; mix until a soft, drop-biscuit dough forms.
5. Assemble & bake:
Drop spoonfuls of dough (about 12–15 portions) over the chicken filling—don’t spread, just drop!
Sprinkle remaining cheese over top.
Bake 30–35 minutes until topping is golden, filling is bubbly, and chicken reaches 165°F (74°C).
6. Rest & serve:
Cool 5–10 minutes. Garnish with fresh parsley and lemon zest. Serve warm.
💡 Pro Tips for Perfection:
Don’t overmix biscuit dough—gentle stirring = fluffy, not dense, drops.
Drop dough on warm filling—helps biscuits rise and “bubble” beautifully.
