Can I make white chicken enchiladas ahead of time?
Yes. Assemble the enchiladas in the baking dish, cover with plastic wrap, and refrigerate up to 24 hours before baking. Add 5–10 minutes to the baking time if baking from cold.
What's the difference between the white sauce and sour cream?
The white sauce is made from butter, flour, and chicken broth (a roux-based béchamel). Sour cream is stirred in at the end to add tang and creaminess without breaking the sauce.
Can I use corn tortillas instead of flour tortillas?
Corn tortillas are more fragile and absorb sauce differently, so the result will be slightly drier and crumblier. Flour tortillas hold together better and are traditional for this dish.
How do I know when the enchiladas are done baking?
Bake at 350°F for 25–30 minutes until the sauce is bubbling at the edges and the cheese on top is melted and light golden. Don't overbake or the tortillas will dry out.
Can I substitute the green chiles?
Yes. Use mild salsa verde, canned diced jalapeños, or roasted poblano peppers. Adjust seasoning to taste as the heat and flavor vary.
