Welsh rarebit is a classic British dish that transforms simple toasted bread into a rich, savory delight. This recipe combines a creamy cheese sauce with the tang of dijon mustard and the umami depth of worcestershire sauce. Perfect for a comforting snack or a quick meal, it's a delicious way to elevate your toast game.
While most of the ingredients for this recipe are common pantry staples, you might need to pick up dijon mustard and worcestershire sauce if they aren't already in your kitchen. These two ingredients add a unique flavor profile to the dish, so they are worth the extra trip to the supermarket.

Ingredients For Real Welsh Rarebit Recipe
Butter: Adds richness and helps create the base of the sauce.
All-purpose flour: Thickens the sauce to the perfect consistency.
Milk: Provides creaminess and smoothness to the sauce.
Dijon mustard: Adds a tangy, slightly spicy flavor.
Worcestershire sauce: Brings a deep, umami taste to the dish.

Technique Tip for This Recipe
When making the cheese sauce, ensure you whisk the flour and butter mixture thoroughly to avoid any lumps.

Suggested Side Dishes
Alternative Ingredients
butter - Substitute with margarine: Margarine can be used as a dairy-free alternative and provides a similar texture and flavor.
all-purpose flour - Substitute with cornstarch: Cornstarch can thicken the sauce just like flour, but use half the amount as it has more thickening power.
milk - Substitute with unsweetened almond milk: Almond milk is a good non-dairy alternative that won't alter the flavor significantly.
dijon mustard - Substitute with yellow mustard: Yellow mustard can be used in place of dijon mustard, though it will be slightly less spicy and complex.
worcestershire sauce - Substitute with soy sauce: Soy sauce can provide a similar umami flavor, though it lacks the tanginess of worcestershire sauce.
sharp cheddar cheese - Substitute with gruyere cheese: Gruyere cheese melts well and has a rich, nutty flavor that complements the dish.
bread - Substitute with whole grain bread: Whole grain bread adds more fiber and nutrients while still providing a sturdy base for the topping.

How to Store / Freeze This Recipe
Allow the cheese sauce to cool completely before storing. This helps prevent 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 you plan to freeze it.
Label the container with the date to keep track of its freshness. The cheese sauce can be stored in the refrigerator for up to 3 days.
For longer storage, place the airtight container in the freezer. The cheese sauce can be frozen for up to 2 months.
When ready to use, thaw the cheese sauce in the refrigerator overnight. This gradual thawing helps maintain the sauce's texture.
Reheat the cheese sauce gently in a saucepan over low heat, stirring frequently to prevent it from separating. If the sauce appears too thick, add a splash of milk to reach the desired consistency.
If you have leftover toasted bread, store it separately in an airtight container at room temperature for up to 2 days. Re-toast before serving to regain its crispness.
Avoid freezing the toasted bread as it can become soggy upon thawing. Instead, prepare fresh toast when you're ready to enjoy your Welsh rarebit.
For a quick meal, you can also store the cheese sauce in individual portions. Use small containers or even an ice cube tray for easy reheating.
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. Bake for about 10-15 minutes, or until the cheese sauce is bubbly and the bread is heated through.
For a quicker method, use a microwave. Place the Welsh rarebit on a microwave-safe plate and 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.
If you have a toaster oven, it's a great option for reheating. Set it to 350°F (175°C) and place the Welsh rarebit inside. Heat for about 10 minutes, or until the cheese sauce is melted and the bread is warm.
For a stovetop method, use a non-stick skillet over low heat. Place the Welsh rarebit in the skillet and cover with a lid. Heat for about 5-7 minutes, or until the cheese sauce is melted and the bread is warmed through. Be sure to check frequently to avoid burning.
If you prefer a crispier texture, use a broiler. Place the Welsh rarebit on a baking sheet and set it under the broiler for 2-3 minutes. Keep a close eye on it to prevent burning, as the cheese sauce can quickly go from perfectly melted to overly browned.
