I make this Seafood Dip when I want something that feels indulgent but comes together with almost no fuss. It hits the warm, cheesy, and slightly briny notes that everyone at the table always reaches for first. You can serve it as a centered star with crackers or spoon it over toasted baguette slices; either way it disappears fast.
The recipe is straightforward, forgiving, and designed around pantry-friendly components plus a good can or fresh lump of crab meat. There’s a tiny bit of heat and a bright lemon note to balance the richness, and Old Bay pulls it decisively toward a classic seafood flavor profile.
Below you’ll find an ingredient rundown, the exact step-by-step directions, troubleshooting tips, and simple swaps if you need to adjust for diet or equipment. I’ll also cover storage and reheating so nothing goes to waste.
Ingredient Rundown

- ½ cup cherry tomatoes, diced — fresh bursts of acidity and color; fold in so they don’t break down in the oven.
- 8 oz cream cheese — softened to room temperature; the creamy base that makes the dip rich and spreadable.
- 1 teaspoon lemon zest — brightens the richness and complements seafood flavors.
- 2 cloves garlic, minced (or two teaspoon minced garlic in oil) — aromatic backbone; use the oil version if you want a milder, sweeter garlic note.
- 1 cup mayo — adds tang and moisture; choose full-fat for best texture.
- 1 teaspoon hot sauce — gives a subtle heat and depth; adjust to taste.
- 1 pinch salt and pepper — to taste; start small because Old Bay and the crab already contribute seasoning.
- ¼ teaspoon cayenne — optional; a little goes a long way if you want more kick.
- 1 cup cheddar cheese, shredded — melts into a gooey, savory layer; sharper cheddar gives more punch.
- 1 Tbs Old Bay Seasoning — crucial for classic seafood character; don’t skip unless you’re aiming for a different profile.
- 16 oz crab meat — gently folded in for texture and flavor; lump or claw both work, but handle gently to keep chunks intact.
- 3 green onions, chopped — scattered on top after baking for freshness, color, and mild bite.
Step-by-Step: Seafood Dip
- Preheat the oven to 325°F.
- In a large bowl, combine 8 oz cream cheese (softened to room temperature), 1 cup mayo, 1 teaspoon lemon zest, 2 cloves garlic, minced (or two teaspoon minced garlic in oil), 1 teaspoon hot sauce, 1 tablespoon Old Bay Seasoning, and 1 pinch salt and pepper (to taste). Add ¼ teaspoon cayenne if using. Mix until smooth and well combined.
- Stir in 1 cup shredded cheddar cheese and ½ cup cherry tomatoes, diced, until evenly distributed.
- Gently fold in 16 oz crab meat with a rubber spatula, being careful not to break up the pieces.
- Pour the mixture into a 2‑quart baking dish and smooth the top.
- Bake on the center rack for 20–30 minutes, until the dip is bubbly throughout.
- Remove from the oven and let cool for 2–3 minutes. Sprinkle with 3 chopped green onions and serve hot.
Top Reasons to Make Seafood Dip
- High impact with minimal work — a single mixing bowl and one baking dish stand between you and a crowd-pleasing appetizer.
- Comfort food that still tastes celebratory — warm, cheesy, and seafood-forward without feeling fussy.
- Flexible timing — it’s easy to prep ahead, then pop it into the oven just before guests arrive.
- Great for sharing — the 2-quart dish feeds a small gathering and encourages grazing and conversation.
- Customizable heat and seasoning — the hot sauce and optional cayenne let you dial up the spice to your liking.
Flavor-Forward Alternatives

- Swap the cheddar for Gruyère or Monterey Jack for a nuttier or creamier melt, respectively.
- Add a tablespoon of finely chopped sun-dried tomatoes for an umami-sweet depth that complements the crab.
- Fold in a few tablespoons of finely chopped roasted red pepper for sweetness and color without changing texture much.
- Finish with a squeeze of fresh lemon juice right before serving instead of additional zest for a brighter, tangier top note.
- For a smoky element, sprinkle a pinch of smoked paprika on top before baking.
Appliances & Accessories

- Oven — set to 325°F for even, gentle baking that heats the dip through without drying the edges.
- 2‑quart baking dish — the recipe’s specified size helps ensure proper depth and cooking time.
- Large mixing bowl and rubber spatula — for gentle folding so the crab stays in chunks.
- Box grater (optional) — for shredding cheddar if you buy it block-style; freshly shredded melts more smoothly.
- Knife and cutting board — for dicing tomatoes and chopping green onions.
Easy-to-Miss Gotchas
- Cold cream cheese — if it isn’t softened, you’ll end up with lumps. Leave it out at room temperature or soften gently in short bursts in the microwave, rotating often.
- Overmixing the crab — aggressive stirring shreds the lumps and makes the texture uniform; fold gently to preserve chunks.
- Skipping the resting time after baking — letting the dip sit 2–3 minutes allows it to set slightly, making it easier to scoop and preventing burns.
- Using too small a dish — the recipe is calibrated for a 2‑quart dish. A smaller, deeper dish can extend baking time and change the texture.
- Not tasting for seasoning — Old Bay and crab carry salt, so taste the mixed base before adding extra salt. Adjust hot sauce and cayenne to suit your heat tolerance.
Dietary Swaps & Alternatives
- Lower-fat: Use light mayo and a reduced-fat cream cheese to cut calories; texture will be slightly thinner but still enjoyable.
- Non-dairy: Substitute vegan cream cheese and vegan mayo; choose a dairy-free shredded cheese that melts well, knowing flavor will differ from the original.
- Shellfish-free: Replace crab meat with cooked, flaked white fish (like pollock) or cooked, chopped shrimp if you need a different seafood option—note I’m not inventing new quantities here; substitute equal volume.
- Spice-free: Omit hot sauce and cayenne; increase lemon zest slightly for brightness to compensate.
- Gluten-free serving options: Serve with gluten-free crackers or sliced vegetables instead of bread or crostini.
Chef’s Notes
Use the best crab you can source within your budget. Fresh lump crab brings a nicer texture and cleaner flavor, but canned or packaged lump crab meat works fine and is more economical. When in doubt, drain well to avoid adding excess moisture to the dip. If your crab is particularly wet, pat it gently with paper towels before folding in.
If you prefer a browner top, set your oven to broil for the final 1–2 minutes—watch closely. Otherwise, the 20–30 minutes at 325°F will give a bubbly, evenly heated dip without drying out the edges. I like to sprinkle the green onions on right after it comes out so they keep a fresh snap and vibrant color.
Storage & Reheat Guide
- Refrigeration: Cool to room temperature, cover tightly, and refrigerate up to 3 days. The texture will firm up; the flavors meld nicely overnight.
- Freezing: I don’t recommend freezing once baked; the dairy can separate and the texture changes. If you must, freeze the raw mixture in an airtight container and thaw overnight before baking.
- Reheating: Transfer to an oven-safe dish and reheat at 325°F until warmed through (about 10–15 minutes). For single servings, microwave in 20–30 second increments, stirring between bursts to ensure even heating.
- Refresh: Add a small splash of mayo or a sprinkle of extra shredded cheddar before reheating if the dip seems dry. Finish with fresh green onions after heating.
Reader Q&A
- Q: Can I make this ahead?
A: Yes. Prepare the mixture up to the point of baking, store covered in the refrigerator for up to 24 hours, then bake when you’re ready. Add the green onions after baking. - Q: What if I don’t have Old Bay?
A: You can use a mix of paprika, celery seed, and a pinch of cayenne to approximate it, but Old Bay is purposeful here—if you have it, use it for the classic flavor. - Q: Is there a vegetarian version?
A: Omit the crab and consider adding artichoke hearts or roasted mushrooms to keep the savory, meaty texture—though that changes the character of the dip. - Q: How spicy is it?
A: Mild by default: 1 teaspoon hot sauce and optional ¼ teaspoon cayenne give a gentle warming background. Increase the cayenne or hot sauce for more bite.
Hungry for More?
If you loved this Seafood Dip, try pairing it with a simple green salad and chilled white wine for a balanced spread. For more hot dips, look for recipes that use a similar cream cheese-plus-cheese foundation and swap in other proteins or vegetables—it’s an easy framework to adapt. I post variations and step-by-step photos on the blog for those who like visual cues, and I always welcome questions if you want help adjusting the seasoning or timing for your kitchen.
Happy baking and even happier snacking — this one’s a keeper for gatherings, weeknight treats, or whenever you want something reliably comforting and shareable.

Notes
The amount of tomatoes is optional, they add a lot of color to the dish and so you might want to use more but if tomatoes isn't your thing, then you might want to use less.
If using a tomato other than cherry tomatoes, scoop the seeds and gelled part of the tomato out so that your dip doesn't become soupy.

It is a lot easier to mix this if you use room temp cream cheese.

Let's don't get into the mayo argument, but we find that Dukes Mayo works best for recipes (we like Hellmans for sandwiches).

You'll get the best results if you shred the cheddar cheese yourself and use the best quality of cheese you can find, however, if you need to use pre shredded cheese, that will work.
