What to Serve With It

Pair this creamy bake with lighter sides to balance out the richness:

• Steamed green beans or roasted broccoli
• Mixed greens with vinaigrette
• Garlic mashed potatoes or buttery rice
• Crusty bread to mop up the sauce
• A glass of crisp white wine or sparkling apple cider

Tips for Success

• Rotisserie chicken = timesaver: Just shred and go.
• Add mozzarella with the Swiss for extra melt.
• Use crushed Ritz instead of breadcrumbs for buttery crunch.
• Make it keto: Skip the topping and use almond flour in the sauce.

Storing & Reheating

• Fridge: Store covered for up to 4 days.
• Freezer: Wrap tightly, freeze up to 2 months. Thaw overnight.
• Reheat: Oven at 350°F for crisp topping, or microwave if short on time.
