Why you’ll love this Stuffed Zucchini Recipe with Ground Beef

Quick to prepare: Most of the work happens on the stovetop while the zucchini bake.
Big on flavor: Toasted fennel, garlic, and a savory seasoning blend lift simple ingredients.
Flexible: Swap the brown rice for cauliflower rice for a lower-carb option (see notes).
Family-friendly: A complete, balanced plate with protein, veg, and grains.

Ingredients

4 large round zucchini (see notes)
1/2 onion, chopped
1 red bell pepper, chopped
2 tsp. olive oil
1 lb. ground beef
1 tsp. Spike Seasoning (or use another all-purpose seasoning blend)
1 tsp. garlic puree (from a jar)
1 tsp. ground fennel seed
1 cup cooked brown rice (see notes for lower-carb option)
1/2 cup finely chopped fresh basil
3/4 cup coarsely grated Parmesan cheese, divided
1/4 cup chicken stock

Notes

If you prefer a lower-carb version, substitute 1 cup cooked cauliflower rice for the brown rice. Keep the amount the same and drain any excess moisture before mixing.
Choose large round zucchini so you have roomy shells for stuffing. If your zucchini are smaller, reduce the number used or make extra filling to serve on the side.
If you cannot find Spike Seasoning, a simple mix of 1/2 tsp salt, 1/4 tsp black pepper, and 1/2 tsp paprika is a good stand-in.
Chicken stock is used to add moisture and depth; use a light vegetable stock if you prefer a non-meat option.

Equipment

Baking sheet or shallow baking dish
Large skillet
Spoon and knife for hollowing zucchini
Mixing bowl

Instructions

Follow these clear, step-by-step directions to make this Stuffed Zucchini Recipe with Ground Beef.

Preheat your oven to 375°F (190°C). Prepare a baking sheet or a shallow baking dish by lightly greasing it or lining it with parchment.
Wash the 4 large round zucchini. Slice the tops off to create a lid and carefully scoop out the flesh with a spoon, leaving about 1/4-inch of shell so the zucchini keep their shape. Reserve the scooped flesh—finely chop it and set aside for the filling.
Heat 2 tsp. olive oil in a large skillet over medium heat. Add 1/2 onion (chopped) and 1 red bell pepper (chopped). Sauté for 4–5 minutes, stirring occasionally, until the vegetables are softened and the edges begin to brown.
Add 1 lb. ground beef to the skillet with the softened onion and pepper. Break the meat up with a spatula and cook until it is browned and no longer pink, about 6–8 minutes.
Once the beef is mostly cooked, stir in 1 tsp. Spike Seasoning (or your chosen all-purpose seasoning), 1 tsp. garlic puree, and 1 tsp. ground fennel seed. Mix thoroughly so the seasonings coat the meat and vegetables. Cook for 1–2 minutes to bloom the spices.
Add the reserved chopped zucchini flesh and 1 cup cooked brown rice to the skillet. Stir to combine and cook 1–2 minutes to warm the rice and reduce any loose moisture.
Pour in 1/4 cup chicken stock and stir. Let the mixture simmer gently for 1–2 minutes so the flavors meld and the filling becomes slightly saucy without being runny.
Remove the skillet from heat. Stir in 1/2 cup finely chopped fresh basil and 1/2 of the Parmesan (about 3/8 cup or half of the 3/4 cup), reserving the remaining cheese for topping.
Season the filling to taste with extra Spike Seasoning or a pinch of salt and pepper if you like. Mix until evenly combined.
Spoon the meat and rice mixture into each hollowed zucchini, pressing gently so they are well filled but not overflowing. Place the zucchini in your prepared baking dish or on the baking sheet so they sit upright and stable.
Sprinkle the remaining Parmesan cheese evenly over the tops of the stuffed zucchini.
Bake in the preheated 375°F (190°C) oven for 20–25 minutes, until the zucchini shells are tender when pierced with a fork and the cheese is melted and lightly golden.
Remove from the oven and let the stuffed zucchini rest for 5 minutes before serving. Garnish with extra chopped basil if desired, and serve warm.

Serving suggestions

Plate each stuffed zucchini with a simple green salad dressed in lemon vinaigrette to cut through the richness.
A spoonful of plain Greek-style yogurt or a drizzle of tomato sauce pairs nicely on the side.
For a heartier meal, serve with crusty bread to soak up any remaining juices.

Make-ahead and storage

To make ahead: Assemble the zucchini and refrigerate uncovered for up to 2 hours before baking. If you need longer storage, cover tightly and refrigerate for up to 24 hours; add an extra 5–7 minutes to the baking time if baking from chilled.
Leftovers keep well in an airtight container in the fridge for 3–4 days. Reheat in a 350°F (175°C) oven for 10–12 minutes or until warmed through. You can also reheat in a covered dish in the microwave, though the shells will be softer.

Tips for success

Don’t over-scoop the zucchini shells. Leaving about 1/4-inch of flesh ensures they hold their shape and don’t collapse while baking.
If the filling seems dry after adding the rice, splash an extra tablespoon or two of chicken stock to reach a moist but not watery consistency.
For deeper flavor, brown the ground beef well and scrape up the browned bits from the pan before adding the seasonings and liquids.
Fresh basil folded in at the end brightens the filling—add it last to preserve its color and flavor.

Final thoughts

This Stuffed Zucchini Recipe with Ground Beef is a dependable weeknight winner that feels special without a complicated ingredient list. The contrast of tender zucchini and rich, aromatic beef-and-rice filling makes every bite satisfying. With a few simple swaps you can tailor this dish to lower carbs or make it lighter—either way, it’s a delicious way to showcase summer produce.

Prep Time15

Cook Time20

Total Time35

Servings: 4 servings

Ingredients

4 large round zucchini see notes
1/2 onion chopped
1 red bell pepper chopped
2 tsp olive oil divided
1 lb ground beef
1 tsp Spike Seasoning or another all-purpose seasoning blend
1 tsp garlic puree from a jar
1 tsp ground fennel seed
1 cup cooked brown rice see notes for lower-carb option
1/2 cup fresh basil finely chopped
3/4 cup Parmesan cheese coarsely grated, divided
1/4 cup chicken stock

Instructions

Cook the brown rice according to package directions, or remove frozen cauliflower rice from the freezer to begin thawing if using the lower-carb option.
Preheat the oven to 375°F (190°C).
Prepare the zucchini: for round (ball) zucchini, trim the stem end so the zucchini sits flat and use a pointed teaspoon or melon baller to scoop out the center, leaving a 1/2-inch thick shell; for long zucchini, trim the ends, cut in half lengthwise, and scoop out a shallow boat, leaving about 1/2 inch of flesh.
Microwave the hollowed zucchini for 3–4 minutes on high to soften slightly, then set aside.
Heat 1 teaspoon olive oil in a nonstick frying pan over medium heat, then sauté the chopped onion and red bell pepper about 3 minutes until slightly softened. If using thawing cauliflower rice, add it now and cook with the vegetables.
Add the Spike Seasoning, garlic puree, and ground fennel seed to the vegetables and cook 1–2 minutes more, then transfer the vegetables to a large mixing bowl.
Add the remaining 1 teaspoon olive oil to the hot pan, add the ground beef, and cook over medium-high heat until browned, breaking it up with a turner; then transfer the cooked beef to the mixing bowl with the vegetables.
Stir the cooked brown rice (or thawed cauliflower rice), chopped basil, 1/2 cup of the grated Parmesan, and the chicken stock into the meat and vegetable mixture until evenly combined.
Lightly oil or spray a roasting pan with sides tall enough to hold the zucchini. Pack the stuffing mixture into each zucchini, mounding it as needed, and place the stuffed zucchini close together in the pan so they support one another.
Roast uncovered for 15 minutes, then sprinkle the tops with the remaining Parmesan cheese and return to the oven.
Roast 10–15 minutes more, until the zucchini are tender-crisp and the filling is hot and lightly browned.
Serve the stuffed zucchini hot.
