Keto Eggplant Rollatini with Ricotta. Soft roasted eggplant slices, creamy ricotta filling, light tomato sauce, and melted mozzarella. Simple steps, low carb, weeknight ready.
2 large eggplants, sliced lengthwise ¼ inch thick
1–2 tsp fine sea salt (for salting slices)
2–3 tbsp olive oil, plus more for finishing
Black pepper
Sauce
2 cups low-carb marinara or crushed tomatoes (no sugar added)
2 tbsp olive oil
2 cloves garlic, minced
1 tsp dried oregano or Italian seasoning
Pinch red pepper flakes (optional)
Salt to taste
Ricotta filling
1 ½ cups whole-milk ricotta
1 large egg
¾ cup grated parmesan (or pecorino)
1 ½ cups shredded low-moisture mozzarella, divided (1 cup in filling, ½ cup on top)
2 tbsp chopped basil or parsley, plus extra for garnish
¼ tsp garlic powder
¼ tsp onion powder
¼ tsp black pepper
¼ tsp fine sea salt
Zest of ½ lemon (optional)
Salt eggplant: Lay slices on trays. Lightly salt both sides. Rest 20–30 minutes. Blot very dry.
Roast slices: Heat oven to 425°F (220°C). Line trays with parchment. Brush slices with olive oil; add pepper. Roast 10–12 minutes, flip, then 5–8 minutes more, until flexible and lightly golden.
Make sauce: Warm 2 tbsp olive oil in a small pot over medium heat. Add garlic 30 seconds. Stir in tomatoes, oregano, pepper flakes, and a pinch of salt. Simmer 10 minutes. Spread ½–¾ cup sauce in a 9×13 in (23×33 cm) baking dish.
Mix filling: In a bowl, stir ricotta, egg, parmesan, 1 cup mozzarella, herbs, garlic powder, onion powder, pepper, salt, and lemon zest. The mix should be thick and creamy.
Roll: Place 1 roasted slice on a board. Add 1–2 tbsp filling near the wide end. Roll toward the narrow end. Set seam-side down in the sauced dish. Repeat with all slices (12–16 rolls).
Top and bake: Spoon remaining sauce over the rolls. Sprinkle the last ½ cup mozzarella. Bake at 400°F (205°C) for 18–22 minutes until bubbling. Broil 1–3 minutes to brown. Rest 8–10 minutes. Garnish with basil and a light drizzle of olive oil.
If ricotta looks wet, mix in 1–2 tbsp extra parmesan.
Too much sauce can make the dish watery; keep it light on top.
Air fryer for slices: 400°F (200°C), 3–4 minutes per side, in batches.
Add-ins: chopped spinach (squeezed dry), sautéed mushrooms, or a spoon of pesto mixed into the filling.
Make ahead: assemble, cover, and chill up to 24 hours; bake 5 minutes longer.
Freezer: assemble but don’t bake. Wrap well and freeze up to 2 months. Bake from frozen at 375°F (190°C) 45–55 minutes covered, then uncover 10 minutes. Add topping cheese in the last 15 minutes.
