Irish Rarebit (St Patrick’s Day Menu Idea) Recipe
Introduction
Irish Rarebit is a delicious twist on the classic Welsh rarebit, featuring rich Irish cheddar melted into a smooth, tangy cheese sauce. Perfect for St. Patrick’s Day or any cozy meal, this dish is easy to prepare and pairs beautifully with toasted bread and pickles.

Ingredients
- 1 oz butter (¼ stick)
- 3 Tbsp milk
- 8 oz Irish cheddar (such as Kerrygold Dubliner or another melty cheese)
- 1 tsp white vinegar
- 1 tsp English mustard (prepared, or substitute your favorite mustard, or omit)
- ⅛ tsp black pepper (freshly grated, to taste)
- 2 Tbsp gherkin (or cornichons, chopped)
- 4 slices bread (good quality, toasted)
Instructions
- Step 1: Melt the butter in a medium saucepan over low heat, then add the milk and grated cheese. Stir continuously until the cheese has melted and the mixture becomes smooth.
- Step 2: Stir in the white vinegar, mustard, black pepper, and chopped gherkins. Combine well and remove the pan from heat.
- Step 3: Let the cheese mixture cool slightly, stirring occasionally to maintain smoothness. Meanwhile, preheat your broiler (grill).
- Step 4: Place the toasted bread slices on a baking sheet and evenly spread the cheese mixture over them.
- Step 5: Broil the cheese-topped toast until the mixture is bubbly and hot, usually a few minutes. Keep a close eye to avoid burning.
- Step 6: Serve immediately, accompanied by extra gherkins or cornichons and a fresh salad if desired.
Tips & Variations
- Use a sharp Irish cheddar for the most flavorful rarebit, or experiment with a mix of cheddar and Dubliner cheese for extra depth.
- For a spicier kick, add a dash of cayenne pepper or a few drops of hot sauce to the cheese mixture.
- Substitute the gherkins with pickled jalapeños for a tangy heat variation.
- If you don’t have a broiler, finish the rarebit under a hot grill or in a hot oven until bubbly.
Storage
Irish Rarebit is best enjoyed fresh, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently in a low oven or microwave until warmed through, though toasted bread may lose some crispness.

Ingredients
Cheese Mixture
- 1 oz butter (¼ stick)
- 3 Tbsp milk
- 8 oz Irish cheddar cheese (such as Kerrygold Dubliner or any melty cheese), grated
- 1 tsp white vinegar
- 1 tsp English mustard (prepared mustard, or substitute your favorite mustard, or omit)
- ⅛ tsp black pepper (freshly grated, to taste)
- 2 Tbsp gherkins or cornichons, chopped
To Serve
- 4 slices good quality bread, toasted
- Extra gherkins/cornichons and salad (optional, for serving)
Instructions
- Melt Butter and Cheese: In a medium saucepan over low heat, melt the butter. Once melted, add the milk and grated Irish cheddar cheese. Stir continuously until the cheese melts completely and the mixture becomes smooth.
- Add Flavorings: Stir in the white vinegar, English mustard, freshly grated black pepper, and chopped gherkins or cornichons. Mix well to combine all the flavors, then remove the saucepan from the heat.
- Preheat Broiler and Prepare Toast: Allow the cheese mixture to cool slightly, stirring occasionally to maintain a good consistency. Meanwhile, preheat your oven broiler (grill). Place the toasted bread slices on a baking sheet.
- Assemble and Broil: Evenly spread the cheese mixture over each piece of toast. Place the baking sheet under the preheated broiler until the cheese topping becomes bubbly and hot, approximately 2-4 minutes. Watch closely to avoid burning.
- Serve: Remove from the oven, place the rarebit toasts on plates, and serve immediately. Accompany with extra gherkins or cornichons and a fresh salad if desired.
Notes
- Use a flavorful Irish cheddar like Kerrygold Dubliner for authentic taste.
- If you prefer a milder cheese sauce, omit or reduce the mustard.
- Keep a close eye under the broiler to prevent the cheese from burning, as broiling times can vary by oven.
- This rarebit is best served immediately while hot and bubbly.
- For a gluten-free version, substitute the bread with gluten-free toast.
