What Makes This Recipe So Good
- Lobster and mashed potatoes are seriously an amazing match you didn’t know you needed to try. Absolutely delicious, this dish is rich, creamy, smooth, and just keeps getting better and better, bite after bite!
- It’s such a special dish and can be served as your main meal or as a side. It’d be a great complement to red meat, such as prime rib or filet mignon. Perfect for any special occasions, dinner parties, the holidays or simply a fun weeknight dinner.
- While lobster mashed potatoes sounds a little fancy, it’s actually super easy to make! It doesn’t require a ton of ingredients, and it comes together in less than 45 minutes.
- To keep this recipe as easy and approachable as possible, I’m using pre-cooked lobster that you can get frozen at most grocery stores. It tastes delicious, and is very convenient. Depending on where you live, finding fresh lobster can be difficult or very expensive. With that said, you can absolutely use fresh lobster for these mashed potatoes if you’d like. You can cook lobster tails in boiling water until bright red, about 5 minutes. Or cook them in the Instant Pot, or even sous-vide.
- Speaking of pre-cooked frozen lobster, make sure it’s fully defrosted before moving on with this recipe. You can place the sealed lobster in the fridge overnight. Or add the lobster to a water resistant zip-top bag, and place it in cold water for about 20 minutes or until fully thawed. Make sure it’s cold water as defrosting any seafood or meat with warm or hot water is not safe.
- For the smoothest mashed potatoes, I always recommend using russet or Yukon gold varieties. They’re nice and starchy so they’ll give you the best texture.
- To get the creamiest mash, peel the potatoes completely before cooking. Add the cubed peeled potatoes to cold water before binging the water to a boil. They’ll cook more evenly that way. When adding potatoes to already boiling water, the outside can cook too quickly while the inside is underdone.
