The ultimate in comfort food, these Red Lobster creamy lobster mashed potatoes are a classic go to side dish for every special occasion.
Everyone loves these creamy lobster mashed potatoes and the recipe begins with an easy method for cooking potatoes in an Instant Pot.
It’s so easy to prepare and cook potatoes in your Instant Pot or pressure cooker. If you don’t have an Instant Pot, no worries, you can easily boil your potatoes on the stove top.
At the same time, we bake Red Lobster style lobster tails in our oven to add to the mashed potatoes after cooking.
Our recipe differs from Red Lobster’s version as we have topped ours with Cajun butter sauce instead of its usual beurre blanc sauce.
This is due to personal preference, since the creamy Cajun butter sauce adds some heat without being overpowering. It is also a little lighter since the sauce isn’t made mostly of pure butter. It’s a flavorful gravy that we really enjoy with these lobster mashed potatoes.
We find it easy to prepare lobster mashed potatoes together with Red Lobster Salmon New Orleans with shrimp. The Cajun butter sauce is just perfect with both dishes at the same time! Win Win.
Although, if serving the lobster mashed potatoes with another entree, you can choose to make it with Cajun butter sauce or use a beurre blanc sauce recipe.

Ingredients in Red Lobster Creamy Lobster Mashed Potatoes
- Lobster — we use lobster meat from our lobster tails recipe,
- Potatoes — washed and peeled, red, white or yellow potatoes. Cut them into quarters or chop them down a little more if they are really large.
- Sour Cream — our preference is full fat sour cream, not low fat or light. Alternatively, you can use Turkish labneh (thick with similar taste to cream cheese) or plain Greek yogurt, store bought or from homemade Instant Pot yogurt.
- Milk — we use homogenized (whole) milk, for a creamier texture.
- Cream Cheese — full fat regular Philadelphia cream cheese is recommended to make this lobster mash extra creamy.
- Butter — salted or unsalted, you might need to add more salt if using unsalted.
- Salt — Himalayan, ground
- Cajun Butter Sauce
- Butter — salted or unsalted.
- Honey — liquid honey is preferred.
- Flour — all purpose.
- Milk — use homogenized (whole) milk for a creamy taste.
- Cajun Seasoning — use our recipe or store bought.
Optional Ingredient Variations
Go ahead and add some fresh sprigs of dill into the water with the potatoes in the first step. Leave the dill sprigs whole or snip them into smaller pieces to impart more flavor.
After cooking, mash the dill together with the potatoes. Dill mashed potatoes are excellent with all your favorite dishes, especially curries and stews!
You can also add garlic clove minced, sliced or whole to the water in the first step, for garlic dill mashed potatoes or add only garlic for garlic mashed potatoes.
Equipment Needed for Red Lobster Creamy Lobster Mashed Potatoes
We typically make this in a 6 quart Instant Pot. You can scale the recipe up or down for an 8 quart or 3 quart Instant Pot.
If you don’t have an Instant Pot, that’s ok. Just Use a large pot on the stove top.
A hand held potato masher is recommended to have to easily mash the potatoes after cooking.

Storage Tips For Red Lobster Creamy Lobster Mashed Potatoes
Keep your cooked mashed potatoes in the fridge for up to four days, however best consumed within two or three days. You can reheat them in an oven in an oven safe dish. Or you can put into a bowl and microwave for 45 seconds or so.
After reheating, you can add a tablespoon or more of milk (depending on the amount of potatoes), and an extra pat or so of butter, to stir in with the potatoes to make them creamy again. The mashed potatoes tend to dry out in the fridge.
With the extra addition of some milk and butter you will think they’re made fresh again.
