Tips & Variations
- For a richer flavor, stir a splash of cream or a dollop of sour cream into the mashed potatoes before baking.
- Substitute kale for the cabbage if you prefer a slightly different texture and taste.
- Try adding cooked bacon or smoked ham for a non-vegetarian twist.
- Use mature cheddar for a sharper taste and a more pronounced cheesy crust.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 350°F (175°C) until warmed through, or microwave in short bursts, stirring occasionally to ensure even heating. The dish is best enjoyed fresh but keeps well for quick reheating.
