How to Serve this Dairy Free Dip

There are so many different ways to serve keto dips! The great thing about this dip is that it’s a delicious appetizer regardless of diet! Because it is Paleo, dairy-free, gluten-free, and keto, it really appeals to all kinds of eaters.

To keep this dip keto and gluten-free, serve with Almond Flour Crackers, Celery or Carrot Sticks, Cucumber rounds, Low Carb Tortillas, or other low-carb, gluten-free chips or crackers.

For your non-keto guests, feel free to serve with crostini’s, a sliced sourdough baguet, ritz crackers, or any type of cracker you prefer. Whether it’s on a veggie or a cracker or simply by itself, this cajun crab dip will hit the spot!

Tips & Tricks

Dairy-Free Swaps: If you’re not dairy-free feel free to swap all non-dairy items in this recipe (cream cheese & nutritional yeast) for their regular counterpart.

Mayonnaise: If you’re looking for the easiest, 60-second homemade mayo, I have the most delicious recipe here!

The Best Crab Meat: Crab meat is great because it’s packed with protein and essential vitamins. This hot cajun crab dip is an excellent keto dip for macros because it’s low in carbs and high in fat and protein. I absolutely love jumbo lump crabmeat. While it can sometimes be a bit pricier than other crab meat, I think it’s the freshest, most delicious crab meat to serve and eat. If you prefer different crab meat, feel free to use it!

Cajun Seasonings: If you can’t make this Old Bay Crab dip because you don’t have Old Bay seasoning on hand, you can use pre-made Creole Seasoning or Cajun Seasoning. Brands like McCormick and many store-bought brands have Cajun seasoning blends that are easy to use! Same quantity for substitutions.

What can I sub for the nutritional yeast?

If you don’t have nutritional yeast on hand, you can sub your favorite regular or dairy-free shredded cheese.

What if I don’t have fresh crab?

Can you freeze crab dip?

Can you use real cream cheese in place of the dairy-free?

Absolutely! If you’re not dairy-free and want to use regular cream cheese for this cajun crab dip, that will totally work!

How to store and reheat leftovers?

Store in an airtight container for up to 5 days. Reheat in the microwave, or re-bake in the oven!

Can I make this a cold crab dip recipe?

Just like the title implies, this hot crab dip recipe is best when served right out of the oven. Unfortunately, it doesn’t work to serve this crab dip cold, as the hot melted flavors combine in the oven to make a killer keto dip. Stay tuned for future recipes- I may just have a cold crab dip coming!
