Recipe Questions & Answers

How do I make this dish vegetarian or vegan?

Use vegetable broth instead of chicken broth and substitute dairy milk and cream with plant-based alternatives like coconut or almond milk. Omit the sausage or replace it with a plant-based version.

Can I prepare this dish without a slow cooker?

Yes, you can simulate slow cooking by simmering the ingredients on low heat in a heavy pot for several hours, stirring occasionally until vegetables are tender.

What type of potatoes work best here?

Russet potatoes are ideal due to their starchy texture, which helps thicken the soup and adds a hearty body.

How do I adjust the spice level?

Modify the amount of Cajun seasoning and cayenne pepper to suit your taste, starting with less and increasing gradually for desired heat.

Can I add proteins like shrimp or chicken?

Yes, cooked shrimp or chicken can be added toward the end of cooking for extra protein and flavor.

What’s the best way to thicken the stew?

Mash some of the potatoes directly in the pot to naturally thicken the broth while leaving chunks for texture.
