Ingredients

- 1 medium head green cabbage (about 1 ½ lbs), cut into large shreds
- 1 cup chopped onion
- 3 ribs celery, chopped
- 2 cloves garlic, minced
- Sea salt and black pepper, to taste
- Use either 2 teaspoons of dried dill or 2 tablespoons of freshly chopped dill
- 2 teaspoons dry mustard powder
- 1 tablespoon lemon zest
- Juice of 1 lemon
- 1 ½ cups heavy cream
- 1 ¼ cups grated Parmesan cheese, divided
- 3 – 5oz cans albacore tuna, drained
- ½ cup frozen peas
Instructions
- Preheat and Prep: Preheat your oven to 375°F (190°C). Grease a large baking dish with some olive oil to prevent sticking.
- Cook the Veggies: In a large skillet, heat the olive oil and butter over medium heat. Add the chopped onion and celery, cooking until they become soft and translucent, about 5-7 minutes.
- Add the Cabbage: Stir in the shredded cabbage, sea salt, and black pepper. Cook until the cabbage is tender, approximately 10 minutes, stirring occasionally.
- Seasonings and Cream: Add the dried dill (or fresh if using), mustard powder, lemon zest, and lemon juice to the skillet. Cook for about 5 minutes, allowing the mixture to thicken slightly.
- Incorporate the Tuna and Peas: Gently fold in the drained tuna and frozen peas. Ensure the tuna is evenly distributed throughout the mixture.
- Cheese it Up: Stir in 1 cup of the grated Parmesan cheese until well combined.
- Baking Instructions: Transfer the mixture into the baking dish. Sprinkle the remaining ¼ cup of Parmesan cheese over the top. Bake in the preheated oven for 25-30 minutes until the casserole bubbles and the top turns golden brown.
- Serving Suggestion: Let the casserole cool briefly before serving. Indulge in this delightful, keto-friendly meal!
