Ingredients
Green Beans: Fresh green beans are best, be sure to rinse and trim them before using. Frozen green beans will also work once they are fully thawed and patted dry.
Oil: Olive oil, coconut oil, avocado oil, or sesame oil are excellent choices. Leftover bacon grease can be used instead of olive oil for a smoky flavor.
Seasonings: Garlic and parmesan cheese add savory flavor to sweet green beans. Pump up the flavor with a simple garlic herb seasoning or a zesty southwestern blend.
Variations
Short on time? Toss green beans in your fave keto Italian dressing and roast as directed in Step 4. In addition to green beans, why not add sliced mushrooms, pearl onions, bell peppers, zucchini, broccoli, or cauliflower florets. A sprinkle of lemon zest can be added, or top with crispy bacon for a real treat.
