Heirloom Tomato Stuffed Portobello Mushrooms with Simple Rarebit

A Simple, Delicious Dish

My wife is an aspiring writer and has a fondness for Cumbria’s Lake District in the UK. She has visited several times and would jump at the chance to live there if the opportunity presented itself. We often watch our local PBS on Sunday nights which features various shows from the BBC.

On one such night, we watched Country House Secrets (S1 Ep4), featuring Mary Berry, in which she tours the great estates of Great Britain. In this episode, Mary visited Goodwood House, where she prepared a simple breakfast for Lord March. The dish is a sautéed portobello mushroom stuffed with a thick slice of sautéed tomato, topped with Welsh rarebit sauce, and is simple enough, though it’s not given on the BBC website, so I am recreating it here.

I was surprised at how delicious this is. The English muffin is essential to catch goodness oozing through the sautéed mushrooms and tomato.

After removing the stem of the portabello mushroom, use a spoon to gently remove the mushroom gills, scraping down towards the center.

Melt the butter and briefly sauté the minced shallots. While this looks like a lot of butter, the mushrooms will act as a sponge.

Cook the mushrooms slowly over medium to medium-low heat to prevent the shallots from browning too much.

The mushrooms should be soft all the way through but still, hold their shape. Reserve and keep warm.

Thickly slice a ripe red tomato. The tomato will need to be thick, so it doesn’t disintegrate while cooking.

Cook the tomato slices over medium heat in the same pan as the mushrooms.

Make a rustic Welsh Rarebit by mixing sharp cheddar cheese with high-quality Dijon mustard and one egg per two servings. Mix the ingredients well. Reserve.

Place the cooked mushrooms on a broiler-safe pan.

Place the cooked tomato slices on top of each mushroom.

Top with the cheese/rarebit mixture and broil in the oven until just browned.

Remove the stuffed mushrooms from the broiler.

Toast an English muffin or thick sliced bread and place it on the serving dish.

Use a spatula to place a stuffed mushroom onto each slice of bread carefully and serve.
