  • 1 (1 lb.) can whole onions, drained
  • 3 Tbsp. flour
  • 1/2 tsp. salt
  • 1 (1 lb.) can cut green beans
  • 1 cup buttered bread cubes

Instructions

  2. Add mustard, Tabasco sauce, salt, and seasonings. Measure bean liquid, add milk to make 1 1/4 cups, and add to the flour mixture.

  4. Pour the mixture into a greased 1-quart casserole dish.
  5. Top with buttered bread cubes.
  6. Bake at 350°F (175°C) for 30 minutes or until the bread cubes are crisp and brown.

Tips & Substitutions

For a creamier texture, consider adding a splash of heavy cream or sour cream to the mixture. If you don't have whole onions, sautéed fresh onions can be used instead for added flavor. You can also substitute green beans with other vegetables like asparagus or broccoli for a twist, making this a versatile dish. For a bit of heat, increase the Tabasco sauce to taste.

Serving Suggestions

Serve this casserole alongside a fresh garden salad for a balanced meal, or pair it with roasted chicken for a comforting dinner. It also complements other vegetarian recipes, making it a great side dish for gatherings. Consider serving with a dollop of sour cream on top for extra richness.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to three days. To reheat, place in a preheated oven at 350°F (175°C) for about 20 minutes, or until warmed through. You can also microwave individual portions, but the bread topping may not stay crisp.

Frequently Asked Questions

Can I use frozen green beans instead of canned?

Yes, frozen green beans can be used in this recipe. Just be sure to thaw and drain them before adding to the casserole to avoid excess moisture. This will help maintain the desired texture of the dish.

What can I substitute for the butter?

If you're looking for a dairy-free option, you can use olive oil or coconut oil instead of butter. For a lower-fat alternative, consider using a light margarine. Just keep in mind that the flavor may slightly differ.
