Oven-Baked Cajun Green Beans (Whole30)

Whole30 Baked Seasoned Green Beans Recipe

The hubs and I are in our second round of Whole30 and we’ve been eating far better than I ever thought we would be. When we were first contemplating doing Whole30, we kept putting it off because we thought we be really restricted on what we could eat. In reality, whole the program is focused on what you can’t eat and eliminating foods from your diet, we’re actually eating a more diverse palette of foods and eating far more veggies than ever before.

Why? When doing Whole30, you’re forced out of your normal food rut and if you don’t want to get bored with your food, it means you need to get creative.

Now, Brian and I don’t ever cook red meat or pork at home. Brian doesn’t eat either at all, and I only eat red meat if we’re dining out. So when cooking at home, that means we’re limited to chicken, turkey, and fish. Oh, and I have a shellfish allergy, so that limits our fish too. This means much of the variety we get comes from seasonings, dressings, side dishes.

Right now, I’m on a roasted vegetable kick, making Sweet Barbecue Roasted Broccoli, Chili Garlic Roasted Broccoli, Garlic And Thyme Roasted Carrots, and Sweet Barbecue Roasted Cauliflower. The latest veggie I’m roasting is the green bean and when seasoned with Cajun seasoning, they are to die for.

Whole30 Recipe For Oven Baked Seasoned Green Beans

Roasting Green Beans In The Oven

You have to be really careful when roasting green beans in the oven. If you overcook them, they’ll get dry and almost hollow-like and the texture is really really weird. I did this once and we ended up tossing the green beans in the trash. Overall, oven-roasted green beans take about 10-15 minutes or so to took, with larger sizes taking longer to cook than the small skinny ones.

Making this tasty side dish is super easy.

Trim the ends of the green beans, place them in a bowl with olive oil, garlic powder, and Cajun seasoning, and toss to coat the green beans evenly with seasoning. Then arrange the green beans on a foil-lined baking sheet and roast for about 5-7 minutes. Remove the baking sheet from the oven, shake it to mix up the green beans, and roast another 5-7 minutes or until the green beans are tender and lightly browned.

Oven-Baked Cajun Green Beans

Fresh green beans take on a whole flavor when roasted in the oven and sprinkled with a spicy Cajun seasoning.

Whole30 Baked Seasoned Green Beans Recipe


  • 1 lb fresh green beans
  • 2 tblsp extra virgin olive oil
  • Garlic powder
  • Cajun seasoning


  1. Preheat an oven to 400 degrees Fahrenheit. Line a baking sheet with foil. Trim the ends of the green beans.
  2. Combined green beans, olive oil, garlic powder, and Cajun seasoning in a bowl and toss to coat the green beans evenly.
  3. Arrange green beans on the baking sheet and roast in the oven for about 5-7 minutes. Remove and shake the pan to mix up the green beans. Roast for another 5-7 minutes or until the green beans are tender and lightly browned.


This recipe says roast for 5-7 minutes each time because I've found that the size of the green beans matters! Small skinny ones take less time to cook than big fat ones.

I don't have a measurement for the garlic power or Cajun seasoning because I likely my foods heavily seasoned and spicy! I just sprinkle on as much as I want! If I had to provide a measurement though, I use about 1 teaspoon garlic powder and 2 teaspoons Cajun seasoning.
