Can I make this ahead of time?
Yes. Assemble the bake up to 24 hours ahead, cover, and refrigerate. Bake straight from cold, adding 5–10 minutes to cook time.
What can I use instead of Swiss cheese?
Gruyère, fontina, or provolone work well. Avoid pre-shredded varieties if possible, as they contain anti-caking agents.
Can I use bone-in chicken instead of breasts?
Yes, but increase baking time to 45–50 minutes and ensure internal temperature reaches 165°F (74°C).
How do I prevent the cream sauce from breaking?
Keep heat moderate when making the sauce, add flour before cream, and whisk constantly to avoid lumps.
What should I serve this with?
Mashed potatoes, egg noodles, or roasted vegetables pair perfectly. A simple green salad balances the richness.
