Tips for the Best Green Bean Casserole
✔ Use Fresh or Frozen Green Beans – Fresh beans give a firmer texture, while frozen ones work great for convenience.
✔ Blanch Fresh Green Beans – If using fresh beans, boil for 3-4 minutes, then drain to keep them tender-crisp.
✔ Don’t Overbake – The casserole should be creamy, not dry, so watch the baking time.
✔ Make It Extra Cheesy – Stir in ½ cup shredded cheese for added richness.
✔ For a Homemade Touch – Replace canned soup with a from-scratch mushroom sauce (see below).
