The BEST way to cook green beans. These rosemary garlic green beans are a simple, versatile 15-minute side dish and an absolute go-to for my weekly meal plans.
A quick steam followed by a 2-minute turn in a hot cast iron skillet produces a fresh, vibrant, crunchy yet tender side dish that will have your guests asking for more.
Here’s everything you’ll need to make these rosemary garlic green beans
- 1 lb greens beans (about 450g or 3 cups)
- Water
- Extra-virgin olive oil or butter
- 3 large garlic cloves
- Fresh rosemary
- Kosher or fine sea salt and freshly ground black pepper
- A squeeze of fresh lemon (optional)
The secret to making the most delicious green beans? Steaming the beans preserves beneficial nutrients that might otherwise be lost during the cooking process. It also helps ensure they retain both their colour and crunchy texture.
You can parboil the beans or even steam them on your stovetop, but I like to keep it simple by steaming them in the microwave. And itās super quick, too!
Notes on preparing the garlic, substitutions and cooking with frozen green beans are included in the recipe card.
Why we love green beans
We grow multiple varieties of beans every year and this dish is a staple served with seasonal meals all year long. They’re super easy to grow, freezer friendly, inexpensive and available in most grocery stores in both the produce and frozen food sections.
Frozen green beans have been harvested at their peak, and weāve come to rely on them, especially during our colder months. We love how versatile they are!
These rosemary garlic green beans pair perfectly with salmon, roast chicken and other proteins and are a natural fit for pasta salads, stir-fries and sheet pan meals. They even make a wonderful, crunchy addition to meal-prepped lunch boxes.
Once you make these rosemary garlic green beans, you may never make them any other way. Crispy, buttery, herbyā¦ delicious!
