Why You’ll Love These Garlic Parmesan Green Bean Casserole Cups

This recipe brings the comforting flavor of traditional green bean casserole into a modern, bite-sized form. The garlic and Parmesan elevate the dish with rich, bold flavor. They’re quick to assemble, easy to serve, and great warm or at room temperature. Plus, no fork is required—just grab and go.

What Kind of Green Beans Should I Use?

Fresh green beans give the best texture and flavor, especially when blanched to keep their vibrant color and crunch. If you’re in a pinch, frozen green beans work well too—just make sure they’re thawed and patted dry before chopping. Canned green beans can be used, but they result in a much softer bite.

Ingredients for the Garlic Parmesan Green Bean Casserole Cups

A great green bean casserole cup starts with the right ingredients. Each one plays an important role in building the creamy, savory, and crispy experience.

• Green beans
• Garlic
• Parmesan cheese
• Cream cheese
• Sour cream
• Cooked mushrooms
• Salt and black pepper
• Mini phyllo cups (or mini tart shells)
• Crispy fried onions

Green beans bring freshness and that iconic crunch. Garlic infuses deep flavor, especially when sautéed with mushrooms. Parmesan cheese gives a salty richness that blends perfectly into the filling. Cream cheese adds a velvety base, while sour cream gives it tang and balance. Cooked mushrooms make the filling earthy and hearty. Season with salt and black pepper to taste. Nestling the mix into mini phyllo cups adds a crisp contrast, and topping with crispy fried onions finishes everything with a craveable crunch.

How To Make the Garlic Parmesan Green Bean Casserole Cups

Step 1: Prep the Green Beans

Trim and chop the green beans into small pieces. Blanch them quickly in boiling water for 3-4 minutes, then transfer to an ice bath to stop the cooking. Drain well and pat dry.

Step 2: Sauté the Aromatics

In a skillet over medium heat, cook diced mushrooms in a bit of butter or oil until browned. Add minced garlic and cook for 1 more minute until fragrant.

Step 3: Mix the Filling

In a bowl, stir together the cooked mushrooms, garlic, green beans, cream cheese, sour cream, and grated Parmesan. Season with salt and black pepper to your liking.

Step 4: Assemble the Cups

Preheat your oven to 375°F. Arrange mini phyllo cups on a baking sheet. Spoon the green bean mixture into each one, filling generously.

Step 5: Bake and Top

Bake for 10-12 minutes until the tops are golden and the filling is bubbly. Remove from oven and sprinkle crispy fried onions on top before serving.

How to Serve and Store These Casserole Cups

These Garlic Parmesan Green Bean Casserole Cups serve around 6 to 8 people, depending on how many you make. They make an excellent addition to holiday spreads, family dinners, or as a side dish at brunch gatherings. Serve them warm for the best flavor and texture, but they hold up surprisingly well at room temperature.

If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To reheat, place them in a 300°F oven for 5-7 minutes until warmed through. Avoid microwaving if you want to keep the phyllo crisp.
