One of our favorite family recipes that draws rave reviews whenever it is served at pre-dinner gatherings is Jarlsberg (yarls-berg) and Caramelized Onion Spread. It is simple, and I have taken photos as it’s being prepared to show you what I mean! The cheese is available at Costco and other grocers who stock good cheeses.
Pre-heat the oven to 350 degrees.
Step 1: Melt about 1 tbsp butter in skillet, add onions, and cook very slowly under low heat, stirring often. A lid on the skillet helps trap moisture. The onions are cooked until they turn translucent and begin to change color.
Step 2: While the onions are cooking, cut up cheese, using a cheese knife to make it easier. Place cheese in a medium sized mixing bowl.
Step 3: When onions are caramelized, stir in the Balsamic vinegar until onions are well coated. Add cheese and toss well.
Step 4: Add enough mayo to bind the mixture together and place in an oven-proof shallow dish to be baked. Cover the bowl with foil and place in middle rack of oven and bake about 30 minutes. Remove foil and continue to bake about 20 more minutes or until mixture is bubbling and cheese appears melted. Blot excess oil from top with a paper towel if needed. (Spread can be covered and refrigerated overnight or until ready to bake and serve.)
Step 5: Serve! Spread is served with a spreading knife on sturdy crackers or French baguettes, toasted.
