Trader Joe’s Green Bean Casserole Recipe

One of my favorite Thanksgiving dishes has always been green bean casserole. There’s something about the creamy filling and crispy topping that just screams “holiday magic.”

This year, I decided to put a twist on the classic version by creating a bite-sized version using Trader Joe’s ingredients. Trust me, these green bean casserole puff pastry bites are a game changer!

Trader Joe’s frozen puff pastry is a lifesaver—it has that buttery, flaky crust that tastes like it’s made from scratch. Inside, you’ll find tender green beans, mushrooms, and a creamy filling. And of course, I didn’t forget the crunchy fried onions on top. Perfect for Thanksgiving or any holiday gathering, these little bites are easy to make and totally irresistible.

Let me show you how to make them step by step.

What Is in Trader Joe’s Green Bean Casserole Recipe?

• 1 sheet of Trader Joe’s Frozen Puff Pastry
• 1 cup green beans or asparagus, chopped into small pieces
• 1 cup mushrooms, finely chopped
• 2 tablespoons olive oil or butter (for sautéing)
• 1 clove garlic, minced
• 1/2 cup crispy fried onions
• 1/2 cup grated cheese (optional; Parmesan or Gruyere work great)
• Salt and pepper, to taste
• 1 egg (for egg wash)

Recipe Substitutions

Don’t have all the ingredients on hand? No worries! Here are some simple swaps you can make:

• Green beans/asparagus: Swap with broccoli, spinach, or even canned green beans for convenience.
• Mushrooms: Use zucchini, bell peppers, or skip them altogether if you prefer.
• Puff pastry: Crescent roll dough or phyllo dough are good alternatives.
• Cheese: Any cheese that melts well can be used—try cheddar, mozzarella, or even vegan cheese if needed.
• Crispy fried onions: Crushed crackers, breadcrumbs, or potato chips can add a similar crunch.

Kitchen Appliance

• Mini Muffin Tin: Essential for shaping the puff pastry bites. If you don’t have one, use a regular muffin tin for larger portions.
• Rolling Pin: Handy for flattening the puff pastry evenly.
• Skillet: A medium-sized skillet works best for cooking the filling.
• Pastry Brush: Helps apply the egg wash for that golden finish.

How to Make Trader Joe’s Green Bean Casserole

Step 1: Prepare the puff pastry

Preheat your oven to 375°F (190°C). Roll out the puff pastry and cut it into small squares (about 2.5 x 2.5 inches). Press each square into a mini muffin tin to form cups.

Step 2: Make the filling

Heat olive oil or butter in a skillet over medium heat. Sauté garlic until fragrant, then add chopped mushrooms. Cook until softened. Add the green beans (or asparagus) and cook for another 3-5 minutes until tender. Season with salt and pepper.

Step 3: Assemble

Spoon the vegetable mixture into the puff pastry cups. Top with grated cheese (if using) and a sprinkle of crispy fried onions.

Step 4: Bake

Lightly brush the edges of the puff pastry with beaten egg for a golden finish. Bake in the preheated oven for 12-15 minutes, or until the puff pastry is golden and crispy.

Step 5: Serve

Remove from the muffin tin and transfer to a serving plate. Serve warm or at room temperature.

Recipe Notes

• Prep Ahead: Make the filling a day in advance and store it in the fridge. Assemble and bake the bites on the day you plan to serve them.
• Cheese Melting Tip: If you want extra gooey cheese, pop the bites under the broiler for 1-2 minutes after baking.
• Puff Pastry Tip: Work quickly with the pastry; it gets sticky if it warms up too much. Chill it in the fridge if needed.

Recipe Variations and Additions

• Spicy Kick: Add a pinch of red pepper flakes or diced jalapeños to the filling for a spicy twist.
• Meaty Option: Add cooked bacon or sausage crumbles for a heartier version.
• Herb Infusion: Mix in fresh thyme or parsley for extra flavor.
• Vegan Version: Use vegan puff pastry, plant-based cheese, and coconut oil instead of butter.

Serving Suggestions

• Appetizers: Serve them at your next holiday party or as a Thanksgiving starter.
• Side Dish: Pair them with roasted turkey, mashed potatoes, and gravy for a complete meal.
• Snack: Enjoy them as a cozy snack with a cup of soup or salad.

Storage Tips

Refrigeration: Store leftovers in an airtight container in the fridge for up to 3 days.
Reheating: Warm them in the oven at 350°F (175°C) for 5-7 minutes to restore their crispiness.
Freezing: Freeze unbaked bites for up to 1 month. Bake straight from frozen, adding 5-7 minutes to the baking time.
