Recipe Notes:

This is a fuss-free method of preparing a traditional Irish meal. The meat and vegetables are cooked to perfection. Do not overcook as Corned Beef can become chewy if cooked too long. This recipe is also good for gluten-free and dairy-free diets.

This Horseradish sauce is light and mild in flavor, not too spicy. If you prefer a spicier sauce, add more horseradish to this recipe. Drizzle this sauce over the corned beef and/or vegetables, as desired. If you prepare the horseradish sauce, it is not gluten-free as written above. Substitute the flour with a gluten-free flour, if needed.
