Shopping List

• 2 large eggplants (about 2 to 2.5 pounds total)
• 1 teaspoon kosher salt (plus more for sweating the eggplant)
• Freshly ground black pepper
• 3 cups no-sugar-added marinara sauce (check labels; aim for 4–6g net carbs per 1/2 cup)
• 4 cloves garlic, minced
• 2 teaspoons Italian seasoning
• 1/2 teaspoon crushed red pepper flakes (optional)
• 1/4 cup fresh basil, chopped (plus extra for serving)
• 2 cups shredded mozzarella cheese
• 1 cup grated Parmesan cheese
• 1 cup whole-milk ricotta (or full-fat cottage cheese, blended smooth)
• 2 tablespoons extra-virgin olive oil
• Nonstick cooking spray or a little oil for the crock

Instructions

1. Prep the eggplant: Slice eggplants into 1/2-inch-thick rounds. Lay them on sheet pans, sprinkle both sides with salt, and let them sit for 20–30 minutes to draw out moisture and bitterness.
2. Blot dry: Pat the eggplant slices thoroughly with paper towels to remove excess moisture and salt.

   This helps prevent a watery final dish.

3. Optional quick sear: For firmer texture, heat a large skillet with 1 tablespoon olive oil over medium-high. Sear eggplant slices in batches, 1–2 minutes per side, adding more oil as needed. This step adds flavor and reduces moisture, but you can skip it if you’re short on time.
4. Mix the ricotta layer: In a bowl, combine ricotta, 1/2 cup Parmesan, 1/2 cup mozzarella, half the basil, and a pinch of pepper.

   Stir until creamy.

5. Season the sauce: In another bowl, stir marinara with minced garlic, Italian seasoning, and red pepper flakes. Taste and adjust salt and pepper.
6. Grease the crock: Lightly coat the slow cooker insert with cooking spray or a little olive oil.
7. Layer 1: Spoon a thin layer of sauce into the bottom of the crockpot. Add a single layer of eggplant slices, slightly overlapping.
8. Layer 2: Dollop small spoonfuls of the ricotta mixture over the eggplant.

   Sprinkle with a handful of mozzarella and a little Parmesan.

9. Repeat: Continue layering sauce, eggplant, ricotta, and cheeses until ingredients are used, finishing with sauce and a generous top layer of mozzarella and Parmesan.
10. Cook: Cover and cook on Low for 4–5 hours or on High for 2.5–3 hours. The eggplant should be very tender, and the cheese should be melted and bubbly around the edges.
11. Rest and finish: Turn off the heat and let it rest, covered, for 15–20 minutes. Sprinkle with the remaining fresh basil before serving.
12. Serve: Scoop into bowls or slice into squares.

    Great with a simple green salad or zucchini noodles for a fuller meal.

How to Store

• Refrigerator: Store leftovers in an airtight container for up to 4 days. The flavors deepen by day two.
• Freezer: Portion into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
• Reheat: Warm in a 325°F (165°C) oven for 15–20 minutes or microwave in 60–90 second bursts until hot.

  Add a spoon of sauce if it looks dry.

Benefits of This Recipe

• Keto-friendly: Low in net carbs, high in satisfying fats and protein from the cheeses.
• Vegetarian main: A hearty meatless option that still feels substantial.
• Hands-off cooking: Minimal active time, perfect for weekdays.
• Nutrient-dense: Eggplant brings fiber and antioxidants; tomatoes add lycopene.
• Budget-friendly: Eggplant and pantry staples keep costs down.

What Not to Do

• Don’t skip salting the eggplant: This step reduces bitterness and prevents watery layers.
• Don’t use sugary sauce: Many jarred sauces sneak in sugar. Choose no-sugar-added to keep carbs low.
• Don’t overfill the crock: Leave at least 1/2 inch of headspace to prevent bubbling over.
• Don’t cook too long: Overcooking can turn the eggplant mushy and the cheese oily. Check at the early end of the time range.
• Don’t skip the rest: Letting it sit after cooking helps it set and slice cleanly.

Variations You Can Try

• Meaty version: Brown 1 pound of Italian sausage or ground beef and layer it with the sauce for extra protein.
• Spinach boost: Add a layer of sautéed spinach or thawed, squeezed-dry frozen spinach for more greens.
• Different cheeses: Swap part of the mozzarella for provolone or fontina.

  Add a little pecorino for a sharper bite.

• Herb-forward: Stir chopped parsley and oregano into the ricotta and finish with fresh thyme on top.
• Zucchini combo: Alternate eggplant with sliced zucchini for extra variety and a different texture.
• Spicy arrabbiata: Use a spicy low-carb marinara and add extra chili flakes for heat.

FAQ

Is eggplant okay for keto?

Eggplant is relatively low in net carbs and high in fiber, making it a great fit for keto when used with low-sugar sauces and full-fat cheeses.

Do I need to peel the eggplant?

No. The skin softens in the slow cooker and adds texture and nutrients. If your eggplants are very large and the skin seems tough, you can peel some or all of it.

Can I make this without ricotta?

Yes.

Use more mozzarella and Parmesan, or blend full-fat cottage cheese until smooth. The texture will still be creamy and satisfying.

How do I prevent a watery result?

Salt and blot the eggplant, avoid watery sauces, and consider a quick sear before layering. Let the dish rest after cooking so juices reabsorb.

What size slow cooker should I use?

A 5- to 6-quart slow cooker works best for these quantities.

If yours is smaller, reduce the ingredients or cook in two batches.

Can I cook it on the stovetop or in the oven?

Yes. Layer in a baking dish and bake at 375°F (190°C) for 35–45 minutes, covered for the first half. For stovetop, use a large covered skillet on low heat and check doneness around 30–40 minutes.

How many carbs are in a serving?

It depends on your sauce and exact portions, but with a no-sugar-added marinara, a generous serving typically lands around 7–10g net carbs.

Always check labels and calculate based on your brands.

Can I assemble it the night before?

You can, but for the best texture, salt and blot the eggplant, then assemble right before cooking. If assembling ahead, keep the ricotta mixture and sauce separate and layer in the morning.

In Conclusion

Keto Crockpot Eggplant Parmesan is the kind of low-effort, high-reward meal you’ll want on repeat. It’s comforting, hearty, and easy to tailor to your tastes while staying low-carb.

With a few smart steps—salting the eggplant, using a clean marinara, and letting it rest—you’ll get a rich, cheesy dish that feels just like classic comfort food. Serve it with a simple salad or zucchini noodles, and dinner’s done.
