Ingredients And Substitutions

If you have any ingredients leftover from this small green bean casserole recipe, check out our Leftover Ingredients Recipe Finder.

  • Green Beans: You can use fresh, frozen (thawed), or canned (rinsed and drained) green beans. A 14-ounce can yields about 2 cups once drained. For fresh green beans, blanch by trimming, cutting into 2-inch pieces, boiling for 2-3 minutes until crisp-tender, then shocking in ice water. If using frozen, a 10-ounce microwaveable bag works well, or pre-cook as directed. Leftover green beans are great in Vegetable Soup or Sautéed Green Beans.
  • Olive Oil: Extra virgin olive oil adds quality and flavor, but light olive oil is a good alternative.
  • Onions and Garlic: Freshly chopped onions and garlic give the sauce a boost in flavor. Alternatively, use 1/8 to 1/4 teaspoon of onion powder and 1/8 teaspoon of garlic powder if fresh isn’t available.
  • Mushrooms: Jarred mushrooms are convenient for small quantities, but fresh mushrooms work well with a slightly longer cook time. Feel free to omit mushrooms if you prefer. Leftover mushrooms can be used in dishes like Risotto, Chicken Marsala, or Coq au Vin.
  • Broth: Chicken broth adds depth, but substitute vegetable broth for a vegetarian option. Leftover broth works well in soups like Tortellini Soup or Beef Stew.
  • Heavy Cream: Heavy whipping cream or heavy cream, both with over 36% milk fat, are ideal for this recipe. Leftover cream can be used in Chicken Alfredo, Apple Cinnamon Scones, or Butterscotch Pudding.
  • Cream Cheese: Adds richness and thickness to the sauce, replacing canned mushroom soup. Use 2 ounces for the perfect consistency. Leftover cream cheese is great in Creamed Spinach or a single serving Cheesecake for dessert.
  • Cheese: Gruyère’s nutty flavor and melting quality work well here. Substitute with Swiss, Fontina, Jarlsberg, or Gouda. Leftover cheese can be used in French Onion Soup, Crustless Quiche Lorraine, or Baked Penne with Roasted Vegetables.
  • Fried Onions: French’s crispy fried onions add flavor, texture, and salt. For a gluten-free option, try gluten-free fried onions from Simple Truth or Garden Farms Organic, or omit if needed.
  • Seasonings: Salt, pepper, and Italian seasoning (a blend of basil, oregano, thyme, and rosemary) enhance the flavors. If Italian seasoning isn’t available, use one or two of these herbs.

Recipe Variations

This small batch green bean casserole is easy to customize, letting you get creative with flavors and textures. Try these variations to make it your own:

  • Bacon: Add cooked, crumbled bacon for a salty, smoky twist. A slice or two is plenty for this recipe.
  • No Mushrooms: If you’re not a fan of mushrooms, simply leave them out—this casserole is just as delicious without them.
  • Nutmeg: Add a subtle layer of flavor by mixing in a pinch of ground nutmeg (less than 1/8 teaspoon) to the sauce.
  • Extra Cheese: For a cheesy green bean casserole, stir in extra cheese. Cheddar or feta are great options to experiment with.
  • Creole seasoning: Add 1/8 to 1/4 teaspoon of Creole or Cajun seasoning for a spicy kick that pairs beautifully with the creamy sauce.
  • Minced Jalapeños: For heat, finely chop a jalapeño pepper and mix 1/2 teaspoon into the onion mixture. Adjust the amount based on your spice preference.
  • Seafood Twist: Add small shrimp or crab meat for a sophisticated seafood flavor. It’s a unique way to elevate this classic dish.

How To Make Green Bean Casserole

These step-by-step photos and instructions help you visualize how to make a small batch green bean casserole. See the recipe box below for ingredient amounts and full recipe instructions.

  1. Prepare the Green Beans (if using fresh or frozen):
  • Bring a medium pot of water to a boil. Add the green beans and blanch for 2-3 minutes, until bright green and tender-crisp.
  • Drain the beans and immediately place them in a bowl of ice water for 1 minute to stop the cooking. Drain again and set aside.

Note: If using canned green beans, simply rinse and drain them—no pre-cooking is needed.


  1. Preheat the Oven: Heat the oven to 350°F (177°C).
  1. Make the Sauce:
  • Heat olive oil in a 10-inch skillet over medium heat. Add onions and cook, stirring frequently, for 2 minutes until translucent.
  • Stir in garlic and mushrooms, cooking for 1 more minute.

    1. Transfer to a Baking Dish:
    • Pour the green beans and sauce into a small baking dish.

    Pro Tip: Use a 4×6-inch baking dish (24 square inches), a 5×5-inch dish (25 square inches), or a 6×6-inch dish for a thinner casserole that may bake faster. A 6.5-inch cast iron skillet also works well.

    Expert Tips

    Frequently Asked Questions

    What size baking dish should I use?

    For this mini green bean casserole recipe, we use a 4×6-inch baking dish that has a base area of 24 square inches.

    Other alternative baking dishes:
    5×5-inch dish
    6×6-inch dish (this will yield a thinner casserole)
    6-inch round dish
    6.5-inch cast iron skillet

    Can I double this recipe?

    Sure, doubling this green bean casserole recipe is a breeze! If you’d like to make more servings, simply double the ingredients. Then, you can either use two 4×6-inch or two 5×5-inch baking dishes, or use a single 9×5-inch loaf pan, a 6.5×6.5-inch baking dish, or a 6×8-inch baking dish.

    Why is my mushroom sauce runny?

    If your sauce is runny, it may not have simmered long enough. After adding the broth, cream, and cream cheese, bring the sauce to a light simmer and stir constantly for about 1 minute. This ensures the sauce thickens properly as some of the liquid evaporates and the cream cheese melts, creating a rich, creamy texture. Stirring is key to achieving the right consistency.

    Can a green bean casserole be made ahead of time?

    Yes!
    Unbaked: Assemble the casserole, leaving off the onion topping. Cover tightly with foil and refrigerate for up to 3 days. Remove from the fridge 30 minutes before baking and bake as directed.
    Baked: Assemble and bake the casserole, but omit the onion topping. Let it cool to room temperature, then cover tightly with foil and refrigerate for up to 3 days. When ready to reheat, bake at 350°F for 10 minutes, add the onion topping, and bake for an additional 5 minutes.

    How do I store leftover green bean casserole?

    Cover and store the leftovers in the refrigerator for up to 3 days. Reheat in the microwave or in the oven at 350° for about 10 minutes.

      Great recipe! My husband and I both loved the flavors of the dish. I used fresh mushrooms as we prefer them over jarred. Perfect size for us and leftovers for the next day.

    2. AZCARMELA says:

      Hello! I just wanted to share with you that the Green Bean Casserole recipe I made for our Thanksgiving dinner turned out wonderfully! I increased the recipe to make 10 servings, hoping it would be enough for around 20 people to have a small portion (as there were lots of kids who wouldn’t eat a full serving), and it was more than enough – we had almost 1/3 of it left over. This was great because we had a second day of Thanksgiving for lunch. The dish was super yummy, creamy, and rich in taste. I was thrilled to have used more homemade options as suggested in the recipe. Overall, it was a great success! Thank you!

    3. Josie says:

      Haven’t tried it yet but I have a question. I have a person who doesn’t like mushrooms. Can I leave them out?

      1. Joanie Zisk says:

        Absolutely! Feel free to leave out the mushrooms, the casserole will still be absolutely delicious.
