This keto Halloween snack board is a big platter of cheddar, orange peppers, cantaloupe and tomatoes arranged into a grinning jack-o'-lantern, with black olives and blackberries for the face. It takes about 15 minutes, needs zero cooking, and it's one of the easiest keto Halloween treats you can put out for a party!

This certainly isn't the first jack-o'-lantern themed low carb food that I've created! And I love making veggie platters and snack trays for all the holidays, like my Owl Veggie Tray. They're easy to make, they're usually pretty healthy, and everybody at the party can dig in, whether they eat low carb or not.
Key Ingredients for a Keto Halloween Snack Board
The whole idea is orange for the pumpkin and black for the face. I had to re-read my post on eating the low carb rainbow for inspiration! Here's what works well:
- Cheddar cheese. The backbone of the board and almost zero carbs. Cube a block yourself rather than buying pre-cut, so the pieces are chunky and hold their shape. Colby, Red Leicester or a smoked orange gouda add variety.
- Orange bell pepper. Sweet, crunchy and low in carbs. Cut it into pieces about the size of the cheese cubes. Mini sweet peppers work too.
- Cantaloupe. Melon is higher in carbs than everything else here, so it's a small supporting player. A few cubes add a pop of juicy sweetness without pushing the board out of keto range.
- Orange grape tomatoes. Orange grape or cherry tomatoes fill the gaps beautifully and don't need any chopping.
- Black olives. Large pitted black olives make perfect triangle eyes and a nose. There aren't many black foods that are low carb, so olives do a lot of the work!
- Blackberries. The lowest-carb berries around, and big ones make a great jagged mouth.
- Optional extras. Carrot sticks (in moderation), pepperoni slices, salami, or crunchy Microwave Pepperoni Chips all fit the orange theme.
How to Build a Keto Halloween Snack Board
Find a round black plate or serving platter, about 10 to 12 inches across. Start layering up the orange components: cheddar cubes, orange bell pepper, cantaloupe and orange grape tomatoes. The ingredients can be randomly scattered on the plate or placed in small groups, it's up to you! Pack them in snugly right to the edge so the pumpkin looks full.

Next, make the eyes, nose and mouth from the black olives and blackberries. Triangles for the eyes and nose, and a zigzag row of berries for the grin. You might need to rearrange the orange layer a little so that the black items stay in place.

And you're done! I like to provide some wooden toothpicks for easy pick-up. I should probably get myself a toothpick dispenser! For a party, a pack of skull Halloween toothpicks is a fun extra touch.
How Much Food Per Person?
The recipe card below makes one 10-inch tray, which serves about 8 people as a snack. That works out to roughly 3 ounces of board food per person, which is plenty when the tray is one of several nibbles on the table.
If the snack board is the main event, say for a movie night or before trick-or-treating, plan on 4 to 5 ounces per person and add something more filling like salami, pepperoni or a dip. For a big crowd, it's easier to make two smaller trays than one giant one: the face stays in proportion and you can put one at each end of the room.
Where to Put It Together
Assemble the tray as close to where you'll serve it as you can. Once the olives and berries are in place, the face shifts easily if you carry the tray across the house or put it in the car. If you're taking it to a party, pack the chopped orange ingredients and the olives and berries in separate containers and build the board when you arrive. It only takes a few minutes.
At home, clear a spot on the counter or table where the tray can sit flat, away from the stove or any warm appliances, since the cheese sweats as it warms up. A dark plate or a slate board makes the orange colors really pop.
Helpful Tips
Cut everything to the same size. Cubes about the size of a grape tomato look neater and are easier to grab with a toothpick. Nothing ends up too big to eat in one bite.
Dry the wet ingredients. Pat the cantaloupe and tomatoes dry with paper towel before they go on the plate. Melon juice can make the cheese soggy and slippery.
Add the black layer last. Blackberries can bleed a little color into the cheese, so put the face on at the last minute if the tray is going to sit for a while.
Keep the cantaloupe portion small. Melon is the highest-carb item on the board. Keeping it to a few ounces is what keeps each serving around 4g net carbs.
Variations
- Kid-friendly board. Use string cheese coins or mild cheddar, cucumber "eyeballs" with an olive slice pupil, and mini sweet peppers. Cut the cheese with small Halloween cookie cutters (bats, pumpkins and ghosts) for extra fun, and skip the toothpicks for little ones.
- Sweet board. Swap the savory items for strawberries, raspberries and blackberries, cubes of cheesecake, stevia-sweetened dark chocolate pieces and a few Halloween Brownies. Homemade Keto Low Carb Gummy Bears in orange and black look great too.
- Charcuterie pumpkin. Add folded salami, pepperoni and prosciutto around the edge of the orange layer for a heartier board.
- Veggie-only pumpkin. Replace the melon with extra orange pepper and add a bowl of ranch in the middle as the pumpkin's nose.
- Different faces. Try a spooky frown, a winking eye or a gap-toothed grin. The kids love designing their own.
Board Add-Ons
Want to turn this into a full Halloween spread? Set a few of these around the tray. My Owl Veggie Tray makes a cute companion platter, and the Halloween Spider Web Dip gives everyone something to dunk into.
For crunch, add a bowl of Low Carb Halloween Chips, and for something warm and hearty, a plate of Low Carb Monster Bites is always a hit.
Make-Ahead Tips
This can totally be prepared in advance! Cube the cheese, pepper and cantaloupe up to 2 days ahead and store each one in its own airtight container in the fridge, with a paper towel under the melon to soak up extra juice.
You can build the orange layer up to 4 hours before the party. Cover it tightly with plastic wrap and keep it chilled. Add the olives and blackberries at the last minute so no color bleeds into the orange and the face looks fresh.
Storing & Freezing
Leftovers keep in an airtight container in the fridge for up to 2 days. Pick out the cantaloupe and berries first, since they soften fastest, and store them separately from the cheese. Don't leave the tray out at room temperature for more than 2 hours.
This board doesn't freeze well. Frozen melon, tomatoes and berries turn mushy when they thaw, and cubed cheese gets crumbly. Use leftover cheese and peppers in omelets or salads instead.

Step-by-Step Instructions
- Pick a round platter, board or plate about 10 to 12 inches across (a black one makes the colors pop). Cut the cheddar, bell pepper and cantaloupe into bite-size pieces about the same size as the tomatoes, then pat the cantaloupe and tomatoes dry with paper towel.
- Build the pumpkin: scatter the cheddar, bell pepper, cantaloupe and tomatoes over the whole plate, either mixed at random or in small clusters, packing them in snugly right to the edge.
- Make the face: press the black olives into the orange layer as triangle eyes and a nose, and line up the blackberries in a jagged row for the mouth. Nudge the orange pieces around them so the face stays in place.
- Serve right away with toothpicks on the side. To make ahead, cover the orange layer and chill for up to 4 hours, then add the olives and blackberries just before serving.
