How to Make Baked Stuffed Onions

Step 1: Prep the Onions
Slice top and bottom off each onion.

Cut halfway down the center (to the middle), then boil in water for 10–15 minutes until soft enough to peel layers.

Drain and let cool.

Step 2: Cook the Filling
In a pan, heat olive oil. Sauté shallot and garlic.

Add ground beef and Italian sausage, breaking up the meat.

Once browned, add spices: salt, pepper, fennel seeds, basil, oregano, onion powder, red pepper flakes, and thyme.

Stir in canned tomatoes, chicken broth, and rice.

Cook until most liquid is absorbed and rice is slightly tender.

Stir in parsley. Remove from heat.

Step 3: Prepare the Sauce
Mix strained tomatoes with chicken broth and salt (if needed).

Taste and adjust seasoning.

Step 4: Assemble the Dish
Spread a layer of tomato sauce on the bottom of a large baking dish.

Fill each onion layer with about 2 tablespoons of meat mixture and roll it up.

Place seam-side down in the dish. Repeat until all filling/onions are used.

Pour remaining tomato sauce over the top.

Step 5: Bake
Cover with foil and bake at 425°F for 30–35 minutes.

Uncover and bake another 20–30 minutes, until onions are golden and caramelized.

Broil last 2 minutes if desired.

Step 6: Finish and Serve
Let cool 10 minutes.

Drizzle with balsamic glaze, olive oil, and fresh parsley. Serve warm!
