5 medium zucchini, trimmed, cut in half, seeds scooped out Should be in the shape of a boat.
2 tbsp olive oil, divided
salt and pepper, to taste
1 lb lean ground beef I used 90%
1 small onion, diced
4 cloves garlic, minced
8 oz baby bella mushrooms, sliced thinly, divided
1 tbsp soy sauce
2 tbsp worcestershire sauce, divided
2 tsp dijon mustard
1 1/2 cup cooked rice Cauli-rice can be used for a keto substitute
5 slices swiss cheese Can use more cheese if desired!
2 tbsp butter

Preheat oven to 375°F
Arrange prepared zucchini in 13x15 inch casserole dish. Rub all of the zucchini halves all over using half of the olive oil. Sprinkle each half with salt and pepper, to taste. Bake for 10 minutes. Set aside.
While zucchini is par-cooking, heat remaining oil over medium-high heat in a large skillet with deep sides. Brown the ground beef, seasoning with salt and pepper. Once mostly browned, after about 5 minutes, add onion, garlic, and half of the mushrooms. Cook until the mushrooms and onions are just starting to become softened, approximately another 5 minutes.
Add soy sauce, half of the worcestershire sauce, all of the dijon, and another pinch of salt and pepper. Mix well. Add rice, stirring to combine with meat, veggies and sauce. Simmer for 5 minutes.
Add meat mixture to zucchini boats. Top each boat with 1/2 of a slice of swiss. Bake 10-12 minutes or until zucchini is fork-tender and cheese is melted. Wipe out the pan used for the filling.
While the zucchini boats finish cooking, melt butter in the same pan used for the meat and vegetable mixture over medium-high heat. Once melted, add remaining mushrooms to the pan, spreading out to avoid over-crowding. Sprinkle with salt and pepper and add remaining worcestershire sauce to the pan. Cook, stirring only occasionally until mushrooms are softened and browned, approximately 5-7 minutes.
Top finished zucchini with sauteed mushrooms. Serve and enjoy!

If you are looking for more of a lower-carb alternative, you could easily substitute cauliflower rice instead of Jasmine rice.
There may be leftover filling. It's delicious by itself, or if you don't want leftover filling, you can use less meat or less rice.
The sauteed mushrooms on top are purely optional, but add a lot of the "shroominess" to the zucchini boats.
If you don't have enough room for the 10th zucchini boat, chop it up and add it in with the meat mixture at the same time you add the onions, mushrooms and garlic.
