Why a Vegan Cajun Boil Works (and Tastes Just Like the Real Thing)
Traditional seafood boils rely heavily on shrimp, crab, or crawfish—but honestly? The real star has always been the seasoning and the rich Cajun butter sauce. The veggies and broth soak up everything, giving you deep layers of flavor without needing seafood at all.
We’re also using classics like:
Cajun seasoning
Vegan sausage for heartiness
Green beans for texture
Potatoes & corn for that authentic boil feel
Green onions for freshness
Olive oil for richness
Lemon juice for brightness
Hot sauce for that heat!
And to level it up even further, we’ll add chicken broth—but vegan, of course. (Vegan “chicken-style” broth is the key to capturing that nostalgic flavor while keeping the dish plant-based.)
Ingredients You’ll Need
Here’s an easy list to help you shop, gather, or prep. This recipe is flexible, so feel free to add whatever veggies you love.
Veggies
2 cups baby potatoes
2–3 ears of corn, cut into small sections
1–2 cups green beans
1 cup mushrooms
1–2 lemons (halved or sliced)
3–4 green onions, sliced
Protein
2–3 vegan sausages, sliced
Liquids & Seasoning
4 cups vegan chicken broth
2–3 tablespoons Cajun seasoning
1 tablespoon hot sauce
2 tablespoons lemon juice
3–4 tablespoons olive oil

Extra spices (paprika, garlic powder, onion powder)
How to Make the Vegan Cajun Boil
This recipe is super simple, and the steps go fast—especially once your veggies are chopped and ready.
1. Bring Your Broth to a Boil
In a large pot (the bigger the better!), pour in your vegan chicken broth. Add:
Cajun seasoning
Lemon juice
A few splashes of hot sauce
A drizzle of olive oil
Crab boil bag (optional)
Bring it to a strong boil. This will be the flavor base that your veggies absorb.
2. Add the Potatoes First
Potatoes need the longest to cook, so drop them in first.
Boil for 8–10 minutes until they're almost tender but not fully soft.
3. Add the Corn, Green Beans & Vegan Sausage
Next, add:
Corn pieces
Green beans
Mushrooms
Vegan sausage slices
Let everything boil for another 2–3 minutes, just until the veggies brighten and the vegan sausage warms through.
4. Prepare Your Cajun Butter Sauce
This is where the flavor EXPLODES. In a separate pan:
Add olive oil or vegan butter
Mix in Cajun seasoning
Sauté 3–4 minced garlic cloves
Stir until it’s rich, red, and aromatic
You should have a glossy, spicy, smoky Cajun butter sauce—the heart of your favorite Cajun seafood boil.
5. Combine Everything
Once your veggies are done, drain MOST of the broth (leave ½–1 cup for moisture).
Pour the Cajun butter sauce over the boiled veggies. Stir gently so everything gets coated.
6. Add Green Onions and Extra Lemon
Top with fresh green onions, slices of lemon, and more Cajun seasoning if you like it spicy.
How to Serve Your Vegan Cajun Boil
Just like any good boil, you can serve this:
In a giant bowl
Spread across a lined table for full Cajun vibes
In individual trays for meal prep
With crusty bread or vegan cornbread
With extra hot sauce on the side!
It’s saucy. It’s messy. It’s delicious.
And best of all? No seafood required.
