I like to make a big beef roast in the slow cooker with a mix of sliced bell peppers and onions. It is cooked slow until the meat tears easily with a fork. I use it to make many meals all week long.

I use it to make tacos, fajitas, quesadillas and of course,  I serve it with Mashed Potatoes and gravy.

I was left during this past week with about 1/2 cup of shredded roast beef and about 1 cup mashed potatoes.  Not enough to make a meal for two but perfect to add to something else.  Shepard’s Pie is my usual go to recipe but today I decided to try something a little different.  I mixed the potatoes and roast together and then stuffed them into a blanched bell peppers.   Cook them in the microwave for a quick meal in less than 10 minutes.

I blanche my bell peppers by putting them in large storage bag and microwaving them for about 5 minutes. Perfectly blanched and ready to fill. 

This recipe was really not very fancy or full of crazy ingredients.  I mixed the roast and potatoes together.  The roast had remnants of peppers and onions so the flavor profile was already established.

I stuffed 4 peppers cut in 1/2 with exactly what I had left over. It was as if I had planned to make it from the start.  It needed a little sauciness so I melted a little square of Swiss Cheese on each bell pepper.  I quickly popped them into the microwave and cooked on high for about 3 minutes.  Once they were finished I let the stuffed peppers sit while I prepared the Sage Browned Butter.

My Leftover Mashed Potato Roast Beef Stuffed Bell Peppers were nearly finished. All they needed was a little Sauce. What sauce should I use I thought out loud. Yes, sometimes I talk to myself in the kitchen. Brilliant ideas come from these weird discussions. Immediately I thought of Sage Browned Butter. It would be perfect.

I learned about the secret flavors of Browned butter with sage from a fellow cooking friend. She had created a recipe using a Sage Browned Butter as a sauce for gnocchi. It was stinking delicious! I was hooked on browned butter.  I even brown the butter for my Rice Krispy treats. It adds such a depth of flavor to everything. You will have to trust me and try it!


Sage Browned Butter

1/4 cup butter (1/2 cube)

4-5 torn leaved of fresh sage

In a small sauce pan melt butter over low heat. Add sage and continue cooking until the butter reaches a rich dark caramel color. Watch closely because it can burn if the heat is too high.

Use immediately. Makes a 1/4 cup sauce. Perfect for drizzling over Leftover Mashed Potato Roast Beef Stuffed Bell Peppers.
