Ingredient Breakdown for Red Lobster Stuffed Mushrooms Recipe

Each ingredient in this copycat Red Lobster stuffed mushrooms recipe plays a specific role in recreating the rich, savory flavor and texture of the restaurant version.

White Button Mushrooms

White button mushrooms are ideal for stuffing because of their mild flavor and sturdy caps. They hold their shape well during baking and allow the seafood filling to shine without overpowering it.

Crab Claw Meat

Crab claw meat provides the signature seafood flavor in this recipe. It’s slightly firmer than lump crab, making it easier to mix into the stuffing without breaking down too much. Pasteurized or pre-cooked crab works best for convenience and food safety.

Onion

Chopped white or yellow onion adds subtle sweetness and depth. Lightly sautéing it before mixing softens the texture and removes any sharp bite.

Red Bell Pepper

Red bell pepper contributes mild sweetness, color, and a slight crunch that balances the creamy elements of the stuffing.

Celery

Celery adds freshness and a classic seafood-stuffing flavor profile. Finely dicing it ensures it blends smoothly without overpowering the mixture.

Goldfish Crackers

Crushed Goldfish crackers act as a binder while adding a buttery, savory note that complements the seafood. They help absorb moisture and give the stuffing its signature texture.

Monterey Jack Cheese

Monterey Jack melts smoothly and adds creaminess without overpowering the crab. Its mild flavor keeps the stuffing rich but balanced.

Garlic Powder

Garlic powder provides a gentle garlic flavor that distributes evenly throughout the mixture without adding excess moisture.

Old Bay Seasoning

Old Bay seasoning is the backbone of the seafood flavor. A small amount goes a long way, enhancing the crab without masking it.

Olive Oil

Olive oil is used to sauté the vegetables and prevent dryness. It also helps carry flavor through the stuffing.

Recommended Equipment for Red Lobster Stuffed Mushrooms

• Mini Muffin Pan: This can help keep your mushrooms from toppling over in the oven and spilling the stuffing.
• Cheese Grater: I’ll be honest, I like to start with a block of cheese whenever I need a more moist variety of cheese and grate my own.
• Knife and cutting board: For dicing the onion and bell pepper.
• Mixing bowl and mixing spoon: I figure using a wooden spoon is very much optional here because I’m not a big fan of having to clean a wooden spoon after using it for a mix that includes meat. The important thing is to have one that makes it easy to evenly mix the crabmeat mixture.

Complete Guide to Preparing Red Lobster Stuffed Mushrooms Recipe

Making Red Lobster Stuffed Mushrooms isn’t terribly difficult. You just have to be careful when working with the mushrooms so the mushroom caps don’t fall apart on you.

Step One: Preheat the Oven

Preheat your oven to 400 degrees Fahrenheit.

Step Two: Prepare the Mushrooms for Stuffing

Start by giving the mushrooms a thorough cleaning. You’ll want to get rid of all the black flecks of growing medium that are likely still on your mushrooms so they don’t affect the flavor.

Why don’t they get rid of that while processing them? Well, mushrooms are way more delicate than potatoes or apples are, which makes it difficult to thoroughly clean them on an industrial level without them falling apart.

For the same reason, you’ll want to be gentle with them while cleaning them. A gentle rub of the surface with your fingers should be enough.

Step Three: Make the Seafood Stuffing

First, sauté the diced onion and pepper in the olive oil. You won’t have to do this very long – just a couple of minutes, until the onion is just starting to turn translucent. It’ll cook the rest of the way when the stuffed mushrooms go in the oven.

Mix onion, bell pepper, celery, crushed crackers, cheese, garlic powder, and Old Bay seasoning in a bowl. The stuffing’s texture is the tricky part, and you may want to adjust amounts to get a texture that isn’t too dry or too soupy. We were told that even half a cup of crushed crackers might make it too dry, for instance, because they can and will absorb some of the moisture.

Cooking Tip: It’s often easier to start with a little less crushed crackers, and then add more if you need them. It can be tough to remove some if you added too much.

Step Four: Stuff Your Mushrooms

First, place the mushrooms in the muffin pan, stem side up, and one per “muffin holder.” You may need a pan with larger “muffin holders” if you’re using a larger variety of mushroom like portobello.

The important thing is to keep them from rolling around on you.

Second, remove stems if they aren’t already removed. Be cautious here – you want to make sure you remove them without removing the bottom side of the mushroom.

(If you plan on making a main dish that includes mushrooms to go with this, slice up the mushroom stems and include them in the amount of mushrooms you need. I like to do that because it reduces waste.)

Third, stuff the caps with mushroom mixture. Try not to overfill or it’ll just run over.

Step Five: Bake the Mushrooms

Bake for about 20 minutes until cheese is bubbly and just starting to turn golden.

Ingredient Substitutions for Red Lobster Stuffed Mushrooms

Even with easy-to-find ingredients, sometimes you need to make a swap based on what you have on hand or dietary needs. The good news? This recipe is flexible, and a few smart substitutions can still deliver delicious, restaurant-style results.

• If you can’t find genuine crab meat in the grocery store, imitation crab would work. Red Lobster will sometimes also sneak in a different shellfish, like shrimp or scallions. (I think it’s just as good as crab!)
• It may also be possible to find vegetarian imitation crab meat that’s been made using hearts of palm, artichoke hearts, or tofu and flavored with nori (a type of seaweed) and often Old Bay. Or you could do without the crab meat altogether and use more cheese, though it’s not quite the same.
• While Red Lobster does use Monterey Jack, any cheese with a good amount of moisture would work. Mozzarella, Brie, or Chèvre (a type of goat cheese) can work in a pinch.
• Did you use all your Goldfish crackers for party mix during the last holiday season? Crushed oyster crackers or Saltines should work just as well. Breadcrumbs can also work in a pinch. (I’ve used gluten-free bread crumbs in this recipe before, and it held up pretty well.)
• If you don’t fancy plain button mushrooms, cremini or portobello mushrooms would also work.

Tips & Tricks for Successful Red Lobster Stuffed Mushrooms

Once you’ve chosen the ingredients and any substitutions that work for you, a few simple techniques can make the difference between good stuffed mushrooms and truly restaurant-quality results.

1. I like to adjust the spices in these stuffed mushrooms to taste. Sometimes I’ll add a little more crab and Old Bay.
2. An easy way to tell if the crab leg meat is genuine is to head over to the seafood department of your grocery store. You’ll often see it in the display case, still in the shell if they have it. Never hurts to ask if they can crack the shell for you.
3. See if you can get the crab meat fully cooked so it flakes more easily when you prepare it to mix in with the other stuffing ingredients.
4. I like to start with a little fewer crushed crackers. I can always add more if I need it.
5. I use a teaspoon to put the stuffing mix in the mushroom caps, so it’s more precise, and you don’t lose a lot of it to the sides of the mushroom.
6. Having the oven light on makes it easy to see how your mushrooms are doing without having to open the oven door.
7. The thing to remember about mushrooms is that they will shrink while cooking, so don’t be surprised if they don’t completely fill the slots in the muffin pan when you get them out of the oven.
8. I like to serve these on a nice tin serving tray while they’re still warm. Remember, these are supposed to be an appetizer, so serving them promptly is best!

(What’s that brown liquid at the bottom of the muffin pan slots when you remove the mushrooms? That’s mushroom juice that rendered out while they were cooking!)

FAQ About Red Lobster Stuffed Mushrooms

Still have questions about making Red Lobster stuffed mushrooms at home? The FAQs below cover the most common concerns, but if you don’t see your question answered, feel free to leave it in the comments. I’m happy to help.

Are mushrooms really that valuable nutrition-wise?

Mushrooms that have been exposed to ultraviolet light are an excellent way to get Vitamin D in your daily diet. According to the National Institute of Health, Vitamin D serves a variety of functions, including support for building strong bones by making it easier to metabolize calcium. This reduces your risk of developing osteoporosis.

Vitamin D also supports the function of your muscles and nervous system. It also supports your immune system’s ability to fight off infections.

According to the Harvard School of Public Health, Mushrooms are a good source of B vitamins, especially B2, B3, folate, and B5. They also provide most of the potassium in this recipe.

What should I know about handling crab?

The University of Florida’s IFAS Extension offers the following tips for handling crab safely:

• Wash your hands thoroughly for at least 20 seconds before handling crab.
• Live crab is best! If buying live crab, make sure its legs move. If that isn’t an option, look for crab meat that has been pasteurized or already cooked.
• Once opened, store the crab in the coldest part of your refrigerator and eat within 7 to 10 days.
• Make sure all cutting boards and utensils used to prepare the crab are clean beforehand, and clean thoroughly after working with the crab.

Oregon State University adds some general tips for working with seafood:

• Buy your seafood only from reputable sources like your grocery store. Also, purchase it last because it is highly perishable.
• Try to keep the seafood separate from the rest of your groceries to avoid cross-contamination. Also, store the seafood in a separate part of the refrigerator, preferably in an airtight container.
• Don’t buy expired seafood! Look for the “sell by” or “use by” date on the container if it comes in a container.

Especially important: Does it pass the “sniff test?” It’s normal for crab to have a mild scent that you’ll probably notice when you first open it, but that smell shouldn’t be super strong. If crab meat has a foul odor, it’s probably gone bad!
