Ingredients 

  • 2 tablespoons olive oil

  • 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!
