• Perfect for a Flavorful Treat!
For the Mayo Mixture
- Mayonnaise – Adds creaminess and flavor; use Kewpie Japanese mayo for the best taste; substitute with Hellman’s or Miracle Whip if unavailable.

- Onion Powder – Adds subtle sweetness and depth; adjust to taste or omit if desired.
- Sugar – Balances acidity from lemon juice; optional and can be left out for less sweetness.

For the Mussels
- Mussels (in the half-shell) – The star ingredient; frozen New Zealand green mussels are recommended for ease.
- Shredded Mozzarella Cheese – Provides a delicious, melting topping; mozzarella is ideal, but other cheeses like cheddar can be substituted.

Step‑by‑Step Instructions for Cheesy Mayo Mussels
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). This high temperature will ensure that your Cheesy Mayo Mussels cook evenly and the cheese gets that delightful golden-brown color. Make sure your oven rack is positioned in the middle to allow for proper heat circulation while baking.
Step 2: Prepare the Mayo Mixture
In a medium mixing bowl, combine mayonnaise, minced garlic, garlic powder, onion powder, sugar, and lemon juice. Stir these ingredients until they form a smooth and creamy sauce. This flavorful mayo mixture will be the star of your mussels, bringing a luscious richness to the dish. Set it aside for later use.
Step 3: Arrange the Mussels
Take your mussels and place them on a baking sheet, shell-side down. Ensure they are spread out evenly without overcrowding, allowing heat to circulate around each one. If you’re using frozen mussels, ensure they are thawed and drained for optimal baking. This setup will prepare for the delicious toppings in the next step.
Step 4: Add the Mayo Mixture
Spoon a generous portion of the creamy mayo mixture over each mussel, ensuring they are well-covered. Use a small spatula or the back of a spoon for ease. This coating will melt beautifully, enhancing the flavor of your Cheesy Mayo Mussels as they bake.
Step 5: Top with Cheese
Sprinkle a generous amount of shredded mozzarella cheese over the mayo-covered mussels. The cheese will melt and create a gooey, savory topping that complements the rich base. Make sure each mussel gets its share to achieve an even, bubbly finish once baked.
Step 6: Bake to Perfection
Place the baking sheet in the preheated oven and bake for about 8-10 minutes. You’ll know the Cheesy Mayo Mussels are ready when the cheese is melted, bubbly, and lightly golden. Keep an eye on them to prevent drying out; a perfectly cooked mussel should be plump and juicy.
Step 7: Serve and Enjoy
Once baked, carefully remove the mussels from the oven. Let them cool slightly before serving, as they will be very hot. These Cheesy Mayo Mussels can be enjoyed as a delicious appetizer or paired with your favorite sides for a delightful meal.

Expert Tips for Cheesy Mayo Mussels
-
Mayo Choice Matters: Using Kewpie Japanese mayo enhances the flavor significantly; opt for it when possible. If not, try a similar creamy mayo.
-
Fresh vs. Powdered Garlic: Fresh minced garlic brings a burst of flavor compared to garlic powder. If spice is a concern, using fresh is preferable for its milder taste.
-
Avoid Overbaking: Keep an eye on your Cheesy Mayo Mussels while they bake. Overbaking can lead to dry mussels; perfect doneness means bubbly, golden cheese without losing moisture.
-
Uniform Shell Preparation: Arrange mussels evenly on the baking sheet to allow for uniform cooking. This prevents some from becoming overcooked while others remain underdone.
-
Temperature Check: Ensure that mussels reach an internal temperature of at least 145°F for safe consumption. Adjust cooking time according to whether they’re frozen or thawed.
-
Garnish for Freshness: Consider adding freshly chopped parsley or green onions before serving for a pop of color and added freshness!

Cheesy Mayo Mussels Recipe FAQs
What kind of mussels should I use?
I recommend using frozen New Zealand green mussels for this recipe, as they are easy to prepare and have a great flavor. If you’re in a pinch, you can also use blanched mussels, which are already cooked and just need to be reheated in the oven.
How should I store leftovers?
Absolutely! Leftover Cheesy Mayo Mussels can be stored in an airtight container in the refrigerator for up to 2 days. When you’re ready to enjoy them again, reheat gently in the oven at 350°F for about 10-15 minutes, until warmed through. This keeps them deliciously creamy without drying them out.
Can I freeze Cheesy Mayo Mussels?
Yes, you can! For freezing, wrap each baked mussel tightly in plastic wrap and then in foil to avoid freezer burn. They can be frozen for up to 1 month. When you’re ready to enjoy, let them thaw in the fridge overnight before reheating in the oven. Just remember, once frozen, they should be consumed within that month for the best taste!
What if my mussels are overcooked?
If you notice your mussels becoming overcooked and dry, it’s often due to baking for too long. To prevent this, keep a close eye during the last few minutes of baking. The goal is bubbly, golden cheese, while the mussels should remain juicy. If they do turn out overcooked, serve with a lemon butter sauce to add moisture back!
Are there any dietary considerations for this recipe?
Certainly! If you or your guests have allergies, be cautious about mayonnaise, as it often contains egg. If you’re looking for a vegan alternative, try using a plant-based mayo instead. Also, keep in mind that mussels are a type of shellfish, so check for shellfish allergies if serving to others.
How do I tell if my mussels are fresh?
Fresh mussels should have tightly closed shells; if any are slightly open, give them a light tap. If they close, they’re alive and good to go! Discard any mussels that are completely open or have broken shells, as they may be spoiled.
