Introduction

Green Bean Casserole Bites are a delightful twist on the classic holiday side dish, perfect for parties or easy snacking. These bite-sized pastries combine creamy green beans, savory mushroom soup, melted cheddar, and crispy fried onions all in a flaky puff pastry cup.

The image shows several small tartlets arranged on a white plate, placed on a white marbled surface. Each tartlet has a golden-brown, crispy shell filled with a warm, orange-colored filling. On top of the filling, there are small pieces of toasted nuts and seeds, adding texture and color contrast with light brown and greenish tones. The tartlets are closely placed and appear bite-sized, with slightly uneven edges giving them a homemade look. The lighting highlights the glossy surface of the filling and the matte, crispiness of the shells. photo taken with an iphone --ar 4:5 --v 7

Ingredients

4 cups cooked cut green beans (cut into 1-inch pieces)
1 can (10.5 ounces) Campbell’s® Condensed Cream of Mushroom Soup or 98% Fat Free Cream of Mushroom Soup
1/2 cup milk
1 1/2 cups shredded white Cheddar cheese (divided)
1 1/3 cups French’s® French Fried Onions (divided)
1 package (17.3 ounces) Pepperidge Farm® Puff Pastry Sheets, thawed

Instructions

Step 1: Preheat the oven to 400°F. In a large bowl, stir together the green beans, cream of mushroom soup, milk, 1 cup of shredded white Cheddar cheese, and 2/3 cup of French fried onions until well combined.
Step 2: Lightly grease two 24-cup mini muffin pans. On a lightly floured surface, unfold one puff pastry sheet and roll it into a 10 by 12-inch rectangle. With the long side facing you, cut the pastry lengthwise into six 2-inch strips. Then cut crosswise into four 2 1/2-inch strips, creating 24 rectangles. Press each rectangle into the muffin pan cups. Repeat with the second pastry sheet to make a total of 48 pastry cups.
Step 3: Fill each pastry cup with about 1 tablespoon of the green bean mixture. Bake for 15 minutes. Meanwhile, combine the remaining 1/2 cup shredded Cheddar cheese and 2/3 cup French fried onions in a small bowl.
Step 4: Remove the muffin pans from the oven and top each bite with 1 teaspoon of the cheese and onion mixture. Return to the oven and bake for an additional 5 minutes, or until the tops are golden brown. Let stand for 5 minutes before carefully removing the bites from the pans.

Tips & Variations

If you only have mini muffin pans that hold 12 bites, bake in batches as needed.
For extra flavor, add a pinch of garlic powder or a sprinkle of fresh thyme to the green bean mixture.
Use low-fat or fat-free cream of mushroom soup to lighten the dish without sacrificing taste.
Serve with a dipping sauce such as ranch or a spicy aioli to add a new dimension of flavor.

Storage

Store leftover Green Bean Casserole Bites in an airtight container in the refrigerator for up to 3 days. To reheat, place the bites on a baking sheet and warm in a 350°F oven for about 10 minutes until heated through and crisp. Avoid microwaving to keep the pastry from getting soggy.

How to Serve

The image shows small bite-sized appetizers arranged on a large white oval plate with a thin red rim. Each appetizer looks like a mini open tart or cup made from a golden-baked pastry shell. Inside each shell, there is a creamy, light beige filling topped with small pieces of orange shrimp and green herbs, probably parsley, adding a fresh and colorful touch. The texture of the pastry looks crispy, while the filling is smooth and moist. The plate is placed on a white marbled surface, with a red and white cloth napkin nearby, creating a warm and inviting setting. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I prepare these bites ahead of time?

Yes, you can assemble the bites and keep them covered in the refrigerator for up to 24 hours before baking. Bake just before serving to ensure the pastry stays crisp.

Can I substitute frozen green beans?

Absolutely. Just make sure to thaw and drain the green beans well before using so the mixture doesn’t become too watery.

Ingredients

Scale

Green Bean Mixture

4 cups cooked cut green beans (cut into 1-inch pieces)
1 can (10.5 ounces) Campbell’s® Condensed Cream of Mushroom Soup or 98% Fat Free Cream of Mushroom Soup
1/2 cup milk
1 cup shredded white Cheddar cheese
2/3 cup French’s® French Fried Onions

Topping

1/2 cup shredded white Cheddar cheese
2/3 cup French’s® French Fried Onions

Pastry

1 package (17.3 ounces) Pepperidge Farm® Puff Pastry Sheets, thawed

Instructions

Prepare the oven and green bean mixture: Preheat the oven to 400°F. In a large bowl, combine the cooked green beans, cream of mushroom soup, milk, 1 cup of shredded cheese, and 2/3 cup of French fried onions. Stir everything evenly to make the filling.
Prepare the puff pastry cups: Lightly grease two 24-cup mini muffin pans (about 1 3/4-inch cups). On a lightly floured surface, unfold one thawed puff pastry sheet and roll it into a 10×12-inch rectangle. Cut the pastry lengthwise into six 2-inch strips, then crosswise into four 2 1/2-inch strips, yielding 24 rectangles. Press each rectangle firmly into the mini muffin cups to form little pastry shells. Repeat with the second sheet to make 48 cups total.
Fill and bake the bites: Spoon about 1 tablespoon of the green bean mixture into each puff pastry cup. Bake in the preheated oven for 15 minutes, until the pastry starts to puff and the filling is hot.
Prepare the topping and finish baking: While the bites bake, mix the remaining 1/2 cup shredded cheddar cheese and 2/3 cup French fried onions in a small bowl. Remove the muffin pans from the oven and evenly sprinkle the topping mixture over each bite. Return to the oven and bake for an additional 5 minutes, or until the bites are golden brown and the topping is melted and crispy.
Cool and serve: Allow the casserole bites to stand for 5 minutes so they set slightly. Carefully remove them from the muffin pans and serve warm as delicious party appetizers or side dishes.

Notes

If you only have mini muffin pans that make 12 minis at a time, bake the bites in batches to accommodate all 48 pieces.
Make sure the puff pastry is well chilled but pliable for easier cutting and shaping into cups.
Use low-fat or fat-free cream of mushroom soup for a lighter version without sacrificing flavor.
These bites are best served fresh but can be stored covered in the refrigerator for 2 days and reheated in the oven to retain crispiness.
For a dairy-free variation, substitute the cheese with a vegan alternative and use a dairy-free mushroom soup.
