Looking for a great recipe for those end of summer larger-than-life zucchini? Here’s a savory stuffed zucchini recipe that combines lean beef, mushrooms and onion for a crave-able dish that will satisfy any meat lover, while being lighter in calories than traditional stuffed zucchinis. It calls for lean beef and also replaces some of the beef with savory baby bella mushrooms. We served it with salsa and a green salad, but it’s also great with a side of farro or brown rice.

This is one of the largest zucchinis I’ve seen. It’s from Coral’s garden in Essex. Not great for sauteing or grilling because of the tough skin, but excellent for stuffing.


Here’s how we made it. Scroll down for the full recipe. First we scraped out the insides & seeds then scored the flesh. Then drizzle with olive oil and roast in a preheated 375 degree oven for approximately 20-25 minutes or until the zucchini is fork tender. The larger zucchini are much tougher than the smaller.

At the same time as the onions and mushrooms are cooking, brown the lean beef and drain any fat. Then combine the mushrooms, onions and beef and remove from heat. Remove zucchini from oven. Add beef mixture to hollowed zucchini.
