We haven’t been to Destin since our children were little.  We have a vacation home 2 hours west in Orange Beach, Al so if we go to the coast we are usually there.  It was fun to revisit some old hot spots and revive some memories

We went to a very gorgeous wedding

There was lots of eye candy


I got lots of decor and tablescape ideas


Waiters served delicious canapes from silver trays during the cocktail hour as we watched the sun setting over the Gulf

It put me in the mood to create some fancy dancy appetizers of my own…

mushrooms with gruyere croutons

Like these French Onion Stuffed Mushrooms with Gruyere and Rosemary Croutons


Not hard to make, but there are a few steps~


Caramelize the onions low and slow until they are a beautiful deep gold, about 20 minutes


While this is happening make the croutons.  I toasted 2 slices of this Rosemary Sea Salt bread from Fresh Market and then cut it up.  You can use french bread and season with rosemary and sea salt, or use some homemade Rosemary Salt.  You can see the post on making it here


When onions are done stir in the broth, sherry and Worcestershire…prepare to swoon, because when these liquids hit the hot skillet full of onions your eyes will roll in amazement and your knees will get weak it smells so good!  Let the onions hang out for about 5 more minutes until the liquid reduces.


Place cleaned and stemmed mushroom caps in an olive oil cooking sprayed pan


Fill with the onion mixture


Top with the seasoned bread crumbs~ Sorry this photo is a little blurry, I was still swooning…


Top the bread crumbs with grated Cheese.  At this point they can be refrigerated for several hours.

Bake and enjoy!

We had these with grilled rib eye steaks and HH was a happy happy man!

Here’s the recipe:


Prep Time 30 minutes
Cook Time 12 minutes
Course Appetizer, Side Dish
Cuisine American, French
Servings 12


  • 8 oz Baby Bella whole mushrooms
  • 1 T butter [real unsalted butter please]
  • 1 large sweet onion diced
  • 1/8 cup double strength beef broth [I use the concentrate in a jar]
  • 5 dashes Worcestershire sauce
  • splash of cooking sherry or white wine
  • 3 oz. Gruyere grated
  • 2 slices crusty bread toasted
  • 1 tsp sea salt
  • 2-3 sprigs fresh rosemary chopped


  • Saute onion in butter on medium low heat for 20 minutes, stirring occasionally until deep golden brown.
  • Add beef broth, Worcestershire and sherry or wine. Stir and cook 5 more minutes to reduce sauce.
  • Clean mushroom caps and remove stems.
  • Place in a baking pan that has been sprayed with olive oil cooking spray. Sprinkle with half of seasonings.
  • Fill cavities with onion mixture. Finely chop toasted bread and top onions. Cover with cheese.
  • Bake for 10-15 minutes at 325 or until mushrooms are soft, then broil for several minutes to brown tops if necessary. Makes about 12.


This makes a great appetizer or side dish with steak
