Creamy Cremini Leek And Lentil Frittata

Sliced cremini mushrooms and sweet leeks folded into lightly beaten eggs with tender brown lentils, enriched with low-fat cottage cheese for a moist, fluffy, and blood-sugar-friendly protein base. A quick oven bake locks in creaminess.

Ingredients

  • 4 large eggs
  • 1/3 cup low-fat milk
  • 1/4 cup low-fat cottage cheese (blended until smooth)
  • 1 cup cremini mushrooms, sliced
  • 1 medium leek, washed and thinly sliced
  • 1/2 cup cooked brown lentils (or canned, drained and rinsed)
  • 1 teaspoon olive oil
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon salt
  • 1/8 teaspoon black pepper

Instructions

Prep and Sauté

  1. Preheat your oven to 175°C (lower temperature helps retain moisture). Lightly grease a small baking dish.
  2. Heat olive oil in a skillet over medium heat.
  3. Add sliced leeks and cook until softened, about 4 minutes.
  4. Add sliced cremini mushrooms and cook until they release their liquid and start to brown, about 5 minutes. Remove from heat.

Combine and Bake

  1. In a medium bowl, whisk eggs, low-fat milk, blended cottage cheese, dried thyme, salt, and pepper until smooth.
  2. Fold in the cooked lentils and the sautéed leeks and mushrooms.
  3. Pour the mixture into the prepared baking dish.
  4. Tent the dish loosely with foil and bake for 15 minutes. Remove foil and bake for another 5 to 10 minutes until the center is just set and the top is lightly golden.
  5. Let rest for 3 minutes before slicing. The residual heat will finish setting the frittata without drying it out.

Notes

  • The low-fat cottage cheese adds moisture and a subtle creaminess without extra fat. Blend it beforehand to avoid lumps.
  • Lowering the oven temperature and tenting with foil prevents the eggs from drying out while still setting fully.
  • For extra moisture, you can add 1/4 cup of finely chopped roasted red pepper (from a jar, patted dry) in step 6.

Variations

  • Swap dried thyme for dried dill or marjoram.
  • Add 1/4 cup of grated low-fat mozzarella on top during the last 5 minutes of baking.
  • Stir in 1/4 cup of drained, diced tomatoes (canned) for a juicier texture.
  • Replace half the cremini mushrooms with diced zucchini (squeeze out excess water first) to add moisture.
  • Use cooked green lentils instead of brown for a firmer bite.

Troubleshooting

  • If the frittata still feels dry, try adding an extra tablespoon of milk or use 2% cottage cheese next time.
  • Overmixing the eggs can incorporate too much air, causing the frittata to puff and then collapse dry. Whisk gently until just combined.
  • Baking too long or at too high a temperature is the most common cause. Use the lower temperature and check doneness with a knife: it should come out clean but moist.
  • If you skip the foil tent, the top may brown too quickly while the inside remains underdone. Always tent for the first part of baking.
