Fiber-Boosted Turkey & Zucchini Stuffed Peppers

In a hurry? I’ve got you — recipe below.

This stuffed pepper recipe has been waiting in my notebook for its moment—and the second I revisited it, I knew: it’s a keeper. Juicy, savory turkey filling meets tender zucchini and just the right herbs, baked into bright bell peppers that are as beautiful as they are nourishing. Light enough for a weeknight dinner but satisfying enough to serve any night of the week, they shine on their own or alongside a simple salad or roasted vegetables. A sprinkle of feta on top is optional but highly recommended—it adds a tangy, salty finish that elevates the whole dish.

A Little Note from My Kitchen

This recipe is inspired by the stuffed zucchini and red bell peppers from Giada De Laurentiis. In her original version, both zucchini and peppers are used as separate vessels, with Parmesan folded into the turkey filling. I simplified the approach by folding the zucchini directly into the turkey mixture, creating a unified, fiber-forward filling that adds moisture and nutrition without extra prep.

Instead of breadcrumbs, I use lupin flakes—they give the filling structure while adding protein and fiber, so the peppers stay tender and well-shaped without being heavy. I’ve also built in a little extra nutrition and binding power with ground flaxseed and optional hemp seeds, keeping the flavors balanced and the texture just right.

A sprinkle of feta on top is optional, but highly recommended—it adds a salty, tangy finish that plays beautifully with the savory filling, especially if you’ve seasoned it well.

Servings: 4

Prep Time: 10 minutes

What You’ll Need

For the peppers:

• 4 large bell peppers, tops removed and seeds cleaned out (any color will work; I used yellow and orange)

For the filling:

• 1 lb ground turkey (see substitutions below)

• 1 medium zucchini, finely diced or shredded

• 1 small onion, minced

• 2 cloves garlic, minced

• 1 egg

• ¼ cup lupin flakes (breadcrumb replacement -- I like Chef's Kiss brand)

• 1–2 tablespoons ground flaxseed

• 1 tablespoon hemp seeds (optional)

• 2–3 tablespoons ketchup (preferably sugar-free and made with minimal, whole-food ingredients—such as Primal Kitchen)

• 1 small carrot, grated (optional)

• 1 teaspoon dried oregano or Italian seasoning

• Salt and pepper to taste

• 1 tablespoon olive oil

For baking:

• ¼ cup water or vegetable broth

• 1–2 tablespoons feta, crumbled (optional topping)

Let’s Make It

Prep the peppers

Preheat oven to 375°F. Cut the peppers in half. Remove the seeds. Lay them cut-side up in a baking dish.

Make the filling

In a large bowl, combine:

• 1 lb ground turkey

• 1 medium zucchini, finely diced or shredded

• 1 small onion, minced

• 2 cloves garlic, minced

• 1 egg

• ¼ cup lupin flakes

• 1–2 tablespoons ground flaxseed

• 1 tablespoon hemp seeds (if using)

• 2–3 tablespoons ketchup

• 1 small carrot, grated (if using)

• 1 teaspoon dried oregano or Italian seasoning

• Salt and pepper to taste

Mix gently until just combined.

👉 The mixture should feel moist but lightly structured—not wet or dense. The lupin flakes will absorb moisture as it bakes.

Stuff the peppers

Divide evenly among peppers, pressing lightly to fill without compacting too tightly.

Bake

Pour water or broth into the bottom of the dish.

Cover and bake for 30–35 minutes.

Remove foil and bake another 10 minutes, until:

• peppers are tender

• tops are lightly browned

• filling is set

Add feta (optional)

Sprinkle on top and return to oven for 5 minutes.

Serve

Let rest a few minutes before serving.

Why This Works

Lupin flakes (the anchor)

Instead of breadcrumbs, lupin flakes create structure while adding protein and fiber. They absorb moisture from the turkey and zucchini, keeping the filling tender—not heavy.

Zucchini in the filling

Acts as built-in moisture insurance, eliminating the need for pre-cooking or added fillers.

Flax + hemp

Support binding and nutrition without making the mixture dense. Think of them as reinforcement—not bulk.

Ketchup + herbs

A small amount balances acidity, sweetness, and savoriness—giving that classic comfort-food flavor without overpowering.

Optional feta finish

A pop of salt and creaminess that lifts the whole dish.

Quick Variations

This filling works beautifully with a variety of ground proteins. Use what you have or what you prefer:

• Ground chicken – mild and similar to turkey, with a slightly softer texture

• Ground beef – richer and more savory; pairs especially well with the feta topping

• Ground pork – more flavorful and juicy; consider reducing the olive oil slightly

• Ground lamb – deeper, more robust flavor; especially good with oregano and feta

• Plant-based ground – works well with the same seasoning; reduce moisture slightly if needed depending on the brand

  
  

Adjust the seasoning (quick guide)

• Beef or lamb: increase oregano slightly and add a pinch of cumin or smoked paprika for warmth

• Pork: add a pinch of fennel seed or black pepper to complement its richness

• Chicken or turkey: keep as written, or add a touch more garlic or herbs for depth

• Plant-based: taste and adjust salt—many brands are pre-seasoned

  
  

👉 No matter which protein you choose, keep the lupin flakes and flax—they’re key to binding the mixture and creating that tender, structured texture without traditional breadcrumbs.

What to Serve With It

These stuffed peppers are hearty on their own, but a few simple sides can make the meal feel complete and balanced:

For extra greens:

• Braised escarole — lightly garlicky, slightly bitter, and the perfect counterpoint to the sweet-savory filling.

• Simple salad — arugula, spinach, or mixed greens tossed with olive oil, lemon, and a touch of salt.

For texture or carbs:

• Crusty bread — a slice to soak up any juices from the peppers.

• Roasted potatoes — crispy on the outside, soft inside, seasoned simply with olive oil, rosemary, and a little garlic.

Finishing touches:

• Sprinkle a few extra hemp seeds or flax seeds over the plate for a subtle nutty crunch.

• Drizzle a tiny bit of olive oil or lemon juice over the feta if using — brightens flavors and makes the dish feel polished.

Plating Tips

• Stand each stuffed pepper upright on a plate for a clean, impressive presentation.

• Serve 1–2 peppers per person, depending on appetite, and nestle greens or roasted vegetables around them for color and contrast.

• If using feta, a small crumble on top right before serving makes the dish look fresh and vibrant.
