The other day I decided to make one of our favourite lasagna, White Sauce Lasagna, if you haven’t tried it, believe me you must give it a taste.

It’s rich and delicious and filled with the best of everything. From Italian Sausages, to Peas and Mushrooms to a fast and easy Homemade White Sauce.

And that is how I came up with these Simple Appetizers. I had some leftover White Sauce, you don’t need much about half a cup maybe less. You could add a little extra extra milk,  flour and butter when making the white sauce just to make sure you have some left over.

Or you could always make a smaller amount just to try these! A cup of milk, one tablespoon of flour and butter with a pinch of salt would probably work. In a small pot melt the butter whisk in the flour and salt, then slowly add the milk, on medium/low heat, stirring constantly until the mixture thickens. Let cool.

I had a roll of Puff Pastry in the fridge, so I rolled it out and using my two and a half-inch round cookie cutter I cut out about 10 rounds.

I topped each round with a teaspoon or two of White Sauce a few mushroom slices, which I was already using in the Lasagna so I sliced up a few extra and sautéed them in a little olive oil with some spices.

And of course topped with a generous sprinkle of Fresh Parmesan Cheese, or your preferred cheese. They baked up in about 20 minutes and I can tell you they were gone in less!

    Notes

    These should really be eaten when made, but if you do have leftovers cover well or place in an airtight container and refrigerate. They should keep for 2-3 days in the fridge.

    1. Is it possible to make these ahead of time and freeze or freeze any leftovers — if any “survive.” I’m looking for a simple appetizer to serve before a lasagna dinner for friends. Think this would work great.

    2. Hi Rosemary, So happy I came upon your site. Everything looks delicious to me! More important after looking at your recipes, I feel we are somewhat alike in the style in which we cook. Your recipes are familiar, and as I read the ingredients, I know ,in a sense, how the finished product might taste. I have been giving cooking classes in my home for a few years now, minus the covid epidemic. The classes are small, four to six guests, usually both men and woman.After we cook , we sit at a long preset table and enjoy our cooking projects. I’m happy to be on board with your site , and look forward to many delicious and beautiful cooking! Lorraine Marsala

      1. Hi Bob, whatever white sauce or also known as Bechamel sauce whichever one you prefer, I also include a recipe in the post. Hope that helps.

    3. Loved your mushroom puff pastries. A tip however. I found that the mushrooms tended to slide off the pastry (white sauce) during the cooking process, so I marked an inner circle on the puff pastry and marked the inside of the inner circle with a fork which had the effect of making a “well” in the centre – which did not puff as much – causing the mushrooms to stay put. Worked a treat
