Welsh rarebit is a classic British dish that elevates the simple concept of cheese on toast to a whole new level. This rich and savory recipe combines a creamy cheese sauce with a hint of mustard and Worcestershire sauce, poured over perfectly toasted bread. It's a comforting and indulgent treat that's perfect for any time of day.
While most of the ingredients for Welsh rarebit are common pantry staples, you might need to pick up Worcestershire sauce if you don't already have it. This tangy, savory sauce adds depth and complexity to the cheese mixture. Additionally, make sure to use sharp cheddar cheese for the best flavor.

Ingredients For Real Welsh Rarebit Recipe
Butter: Adds richness and helps create the base of the sauce.
All-purpose flour: Used to thicken the sauce.
Milk: Provides the creamy texture for the cheese sauce.
Sharp cheddar cheese: The main ingredient for the cheese sauce, offering a strong and tangy flavor.
Dijon mustard: Adds a subtle kick and enhances the overall flavor.
Worcestershire sauce: Brings a savory, umami depth to the sauce.
Bread: The base for the dish, best when toasted to a golden brown.
Technique Tip for This Recipe
To achieve a velvety smooth cheese sauce, ensure you whisk the milk in gradually. This helps prevent lumps from forming. Additionally, using sharp cheddar cheese not only provides a robust flavor but also melts more uniformly, resulting in a creamier texture.

How to Store / Freeze This Recipe
- Allow the cheese sauce to cool completely before storing. This prevents condensation, which can make the sauce watery.
- Transfer the cooled cheese sauce into an airtight container. Make sure to leave a little space at the top to allow for expansion if freezing.
- For short-term storage, place the container in the refrigerator. The cheese sauce will keep well for up to 3 days.
- If you plan to freeze the cheese sauce, label the container with the date. This helps you keep track of its freshness.
- When ready to use, thaw the cheese sauce in the refrigerator overnight. Avoid thawing at room temperature to prevent bacterial growth.
- Reheat the cheese sauce gently in a saucepan over low heat, stirring frequently to maintain its smooth texture. If the sauce appears too thick, add a splash of milk to reach the desired consistency.
- Store the toasted bread separately in an airtight container at room temperature. For best results, consume within 2 days.
- If you need to store the toasted bread for longer, wrap each slice tightly in plastic wrap and place them in a freezer bag. Freeze for up to 1 month.
- To reheat frozen toasted bread, pop the slices in a toaster or warm them in an oven preheated to 350°F (175°C) for about 10 minutes.
- Assemble the Welsh rarebit by pouring the reheated cheese sauce over the warmed toasted bread just before serving.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover Welsh rarebit on a baking sheet and cover it loosely with aluminum foil. Heat for about 10-15 minutes or until the cheese sauce is bubbly and the bread is warmed through.
For a quicker method, use a toaster oven. Set it to 350°F (175°C) and place the Welsh rarebit inside. Heat for 8-10 minutes, keeping an eye on it to ensure the cheese doesn't burn.
If you prefer the microwave, place the Welsh rarebit on a microwave-safe plate. Cover it with a microwave-safe lid or another plate to prevent splattering. Heat on medium power for 1-2 minutes, checking halfway through to ensure even heating.
For a stovetop method, place a non-stick skillet over medium-low heat. Add the Welsh rarebit and cover the skillet with a lid. Heat for about 5-7 minutes, or until the cheese sauce is melted and the bread is warmed through.
