Notes

Fresh vs. Canned: For an even fresher taste, substitute canned green beans with blanched fresh green beans.
Seasoning Adjustments: Taste and adjust the soy sauce and pepper as needed.
Extra Creaminess: If you prefer a creamier texture, you can add an extra 1/4 cup of milk.
Onion Watch: Keep a close eye on the French-fried onions during the final bake—they can quickly go from perfectly crisp to overly browned.
Serving Suggestion: This dish is best served warm directly from the oven and pairs wonderfully with turkey or roast beef at holiday meals.
