Practical Tips for the Best Casserole

• Use the large can of green beans (28 oz.) or two smaller ones.
• Want it fresher? Swap canned for blanched fresh or frozen green beans.
• Use skim, 1%, 2% or even almond milk—it won’t affect the flavor.
• Don’t skimp on the onions—extra crunch makes it better!
• To keep it crisp, bake just before serving instead of prepping the day before.

Recipe Variations

Try these fun twists to make it your own:

• Homemade Cream of Mushroom Soup → skip the can and make a from-scratch base.
• Cheesy Upgrade → stir in ½ cup shredded cheddar before baking.
• Healthy Swap → use low-sodium soup and reduced-fat milk.
• French Onion Twist → add caramelized onions for deeper flavor.
• Slow Cooker Version → free up oven space during the holidays.

Storage & Reheating

• Fridge: Store leftovers in an airtight container up to 3–4 days.
• Reheat: For best results, reheat in the oven at 350°F for 10–15 minutes to restore crispiness.
• Microwave: Works too, but onions will soften.
