(full list of ingredients in the recipe card)

• Frozen Whole Green Beans: The star of the show! Frozen beans work wonders because they’re stored at peak ripeness, allowing them to retain a lot of nutrients. You can use french cut or frozen cut green beans, both will do! 
• Kosher Salt and Black Pepper: The dynamic duo for great flavor. Sea salt also works if that’s what you have.
• Salted Butter: Adds richness and helps the spices cling to the beans. 
• Fresh Garlic: A little diced garlic brings a lot of flavor to the dish.
• Cajun Seasoning: This bold spice blend brings a smoky, savory kick with hints of garlic, paprika, and a touch of heat. It adds depth and subtle spice, elevating the green beans from simple to sensational.
• Lemon Juice: just a squeeze of lemon juice adds a nice brightness to the veggies and brings all of the flavors together.
• Sliced Almonds: The garnish you didn’t know you needed! Adds crunch and a subtle nutty flavor. You can also use almond slivers if that is all you can get your hands on.

Substitutions and Variations

Feeling adventurous? Here are a few ways to shake things up:

• Swap the almonds: If you’re not a fan or are allergic, try parmesan cheese or toasted breadcrumbs for a different texture.
• Add a squeeze of lemon: Brighten the dish with a touch of acidity.
• Don’t have Cajun seasoning? Swap it for something else in your spice cabinet, italian seasoning or Mrs. Dash are great subs.
• Make it spicy: drizzle some hot sauce or sprinkle on some red pepper flakes on top.

How to Make Roasted Green Beans

Step 1: Preheat your oven to 425°F. While it heats up, line a large baking sheet with parchment paper. Spread your frozen green beans out in a single layer. Drizzle them with extra virgin olive oil and sprinkle with kosher salt and black pepper. Roast on the top rack of the preheated oven for 15-20 minutes, keeping a close eye so they don’t burn. You’re looking for golden brown edges and extra crispy green beans.

Step 2: While they’re roasting, melt butter in a skillet over medium heat. Add the diced garlic, lemon juice, and Cajun seasoning, cooking until fragrant (2-3 minutes). Set aside.

Step 3: Once the beans are done roasting, toss them in the garlic butter mixture.

Step 4: Transfer to a serving plate and top with sliced almonds for a final touch of nutty flavor. Garnish with flaky sea salt (optional).

Tips for Perfect Green Beans

• Don’t overcrowd your pan. Use a large baking sheet or split the green beans between two baking sheets if you need more room. Overcrowding the pan prevents the beans from crisping up.
• Don’t skip the parchment paper. It prevents sticking and makes cleanup a breeze. You can also use aluminum foil, just make sure to spray the foil so that the green beans don’t stick. 
• Toss in garlic butter immediately. The warmth from the beans will absorb all that buttery goodness.

How to Serve Green Beans

These roasted green beans pair beautifully with almost any main dish. They’re a fantastic choice to serve alongside proteins like smoked chicken, salmon, or a juicy steak.

If you’re putting together a veggie medley, adding glazed carrots, sauteed asparagus, or roasted brussels sprouts can add a ton of flavor and color to any dish. For an extra flavor boost, try topping the beans with a sprinkle of parmesan cheese or even a drizzle of sauteed mushrooms alongside croissant stuffing for added texture and flavor.
