Dad always insisted on making these when the whole family got together. Only 3 ingredients for a melty, savory appetizer that steals the show.

This low carb 3-ingredient pesto cheese bake is exactly the kind of thing my dad would insist on making whenever the whole family got together. It’s ridiculously simple—just mozzarella, pesto, and a drizzle of olive oil—but it comes out of the oven melty, bubbly, and so savory that everyone hovers over the dish with crackers and veggie sticks in hand. It’s perfect for busy nights when you want something impressive without a lot of fuss, and it fits right in with lower-carb snacking or appetizer spreads.

Serve this hot and bubbly, straight from the oven, with low-carb dippers like cucumber rounds, bell pepper strips, cherry tomatoes, and celery sticks. If you’re not strictly low carb, it’s amazing with crostini, pita chips, or a torn baguette. I like to set it in the center of a big board with the veggies and crackers around it, plus a small bowl of olives or salami slices for a more filling appetizer spread. It also works as a side next to grilled chicken or steak, where you can spoon the cheesy pesto goodness right over the top.

Servings: 6

3 cups shredded low-moisture part-skim mozzarella cheese

Preheat your oven to 400°F (200°C). Lightly grease a medium ceramic baking dish (about 8x8 inches or similar) with a little of the olive oil so the cheese doesn’t stick.

Spread the shredded mozzarella cheese in an even layer across the bottom of the baking dish, then gently mound it up into small, rustic piles or mounds so you get individual melty portions. Leave a little space between the mounds so the edges can get bubbly and browned.

Spoon small dollops of the basil pesto over the tops of the cheese mounds, then use the back of the spoon to lightly swirl the pesto into the surface of the cheese. Don’t overmix—you want visible streaks of bright green running through the white cheese.

Drizzle the remaining olive oil over the tops of the mounds, focusing on any spots that don’t have much pesto. This helps the cheese brown nicely and gives those pretty little oil pools on top once it’s baked.

Place the baking dish on the middle rack of the preheated oven and bake for 12–15 minutes, or until the cheese is fully melted, bubbling all over, and golden brown around the edges. If you like extra browning, you can switch to broil for the last 1–2 minutes, watching closely so it doesn’t burn.

Remove the dish from the oven and let the pesto cheese bakes sit for 5 minutes to settle slightly. Serve warm, scooping up individual mounds with a small spatula or spoon, and enjoy with your favorite low-carb dippers or crusty bread if you’re not counting carbs.

You can tweak this ultra-simple recipe in a few fun ways without losing the 3-ingredient spirit. Try using different cheeses: part of the mozzarella can be swapped for provolone or Monterey Jack for a slightly different melt and flavor, or use fresh mozzarella torn into pieces for a softer, creamier texture (just know it may release a bit more liquid). If you’d like a sharper bite, sprinkle a little grated Parmesan over the top before baking—this technically makes it a fourth ingredient, but it does add a nice salty crust. For a flavor twist, use sun-dried tomato pesto or a spinach pesto instead of classic basil. If you’re cooking ahead for a party, you can assemble the cheese and pesto in the dish up to 1 day in advance; cover tightly and refrigerate, then drizzle with olive oil and bake just before serving, adding a couple of extra minutes to the bake time if it’s going in cold. For a slightly more portion-controlled version, divide the mixture into greased muffin tins to make individual cheese bakes—just check early, as they may cook a bit faster. Food safety tips: keep the pesto refrigerated until you’re ready to use it, especially if it’s homemade and contains fresh basil and garlic. Don’t leave the baked dish out at room temperature for more than 2 hours; if you have leftovers, cool them quickly, then refrigerate in an airtight container and reheat in a low oven until warmed through. Because this is mostly cheese and oil, it will be very hot right out of the oven, so let it rest a few minutes to avoid burns when scooping or dipping.
