• Servings: 4
• Calories: 425 per serving
• Carbs: 8g net
• Difficulty: Easy
• Best For: Meal prep, family dinners, keto diet

Why This Works

• Double Cheese Hack: Mixing cottage cheese with store-bought alfredo creates a protein-rich sauce that doesn’t separate when baked
• Perfect Layering: Starting with broccoli on the bottom lets it steam properly while protecting it from burning
• Pre-Cooking Matters: Browning the chicken first creates a flavor base and ensures even cooking
• Temperature Control: 375°F hits the sweet spot for melting cheese without drying the chicken

Ingredients & Smart Swaps

Base Recipe:
• 1½ lbs chicken breasts, cubed
• 2 tbsp olive oil
• Seasonings: onion powder, garlic powder, salt
• 16 oz broccoli florets
• 1 cup alfredo sauce
• 1 cup cottage cheese (4%)
• 1 cup shredded parmesan
• 1 cup mozzarella

Smart Substitutions:
• Chicken thighs work great (same cooking time)
• Cauliflower can replace broccoli
• Greek yogurt + heavy cream can sub for cottage cheese
• Fresh garlic (3 cloves) instead of powder
• Avocado oil instead of olive oil

Avoid:
• Pre-shredded cheese (doesn’t melt well)
• Fat-free cottage cheese (gets grainy)
• Frozen broccoli (too watery)

Step-by-Step Instructions

1. Prep (5 mins):

   • Preheat oven to 375°F
   • Grease 9×13″ baking dish
   • Cut chicken into 1-inch cubes
   • Process cottage cheese until smooth

2. Season & Cook Chicken (10 mins):

   • Season chicken generously with garlic powder, onion powder, salt
   • Heat oil in large skillet over medium-high
   • Cook chicken until golden brown (about 6-8 mins)

3. Make Sauce (5 mins):

   • Mix processed cottage cheese with alfredo
   • Add ½ tsp each: garlic powder, onion powder
   • Season with salt to taste

4. Layer & Bake (25-30 mins):

   • Layer broccoli in dish
   • Add cooked chicken
   • Sprinkle parmesan
   • Pour sauce mixture
   • Top with mozzarella
   • Bake 25 mins until bubbly
   • Broil 1-2 mins for golden top

Pro Tips & Common Mistakes

1. Let dish rest 5-10 minutes before serving (sauce thickens)
2. Cut chicken pieces uniform size for even cooking
3. Don’t skip processing the cottage cheese
4. Season each layer, not just the top
5. Watch closely during broiling – cheese burns fast

Storage, Freezing & Reheating

• Fridge: Keeps 3-4 days in airtight container
• Freezer: Up to 2 months (wrap tightly)
• Reheat: 350°F for 15-20 mins covered with foil
• Microwave: 2-3 mins, stirring halfway
• Add splash of cream when reheating to refresh sauce

Variations

1. Mexican Style: Add taco seasoning, pepper jack cheese
2. Mediterranean: Mix in sundried tomatoes, spinach, feta
3. Buffalo: Add buffalo sauce to alfredo, top with blue cheese
4. Mushroom Lover’s: Add sautéed mushrooms between layers

FAQ

Can I make this ahead?

Yes! Assemble up to 24 hours ahead, store covered in fridge. Add 5-10 minutes to bake time.

Why is my sauce watery?

Usually from underprocessed cottage cheese or frozen broccoli. Use fresh broccoli and blend cottage cheese until completely smooth.

Can I use rotisserie chicken?

Yes – skip the chicken cooking step. Shred or cube about 3 cups cooked chicken. Layer as directed.
