Ingredients & Substitutions

Ingredient List

Here’s what you’ll need to bring these keto stuffed peppers to life:

• 4 large bell peppers (any color)
• 1 lb ground beef
• ½ lb ground pork (or use all beef if preferred)
• ½ cup chopped walnuts
• 1 small onion, finely diced
• 2 garlic cloves, minced
• ½ cup riced cauliflower (fresh or frozen)
• ½ zucchini, grated
• ¼ cup tomato paste
• 1 tsp dried oregano
• 1 tsp smoked paprika
• Salt and pepper to taste
• 1 cup shredded mozzarella or cheddar cheese
• Fresh parsley for garnish (optional)

Notes on Quality

• Bell peppers: Choose firm, brightly colored ones that can stand upright easily.
• Walnuts: Toasting them briefly before adding enhances flavor and crunch.
• Cheese: Use a blend for extra flavor—mozzarella for meltiness, cheddar for sharpness.

Possible Substitutions

• No pork? Use all beef or ground turkey.
• Nut-free? Skip the walnuts and add a bit more riced cauliflower or diced mushrooms.
• Dairy-free? Sub in a vegan cheese or nutritional yeast.

Step-by-Step Instructions

1. Preheat oven to 375°F (190°C). Prepare a baking dish by lightly greasing it.
2. Prepare the peppers: Slice off the tops and remove seeds. Set aside.
3. Sauté the filling: In a large skillet, cook onions and garlic in a bit of oil over medium heat until fragrant. Add the ground beef and pork. Cook until browned.
4. Add veggies and flavor: Stir in zucchini, riced cauliflower, tomato paste, walnuts, and seasonings. Cook 5–7 minutes until everything is well incorporated and soft.
5. Stuff the peppers: Spoon the filling into each pepper. Don’t pack too tightly.
6. Top with cheese: Generously sprinkle shredded cheese over the top.
7. Bake for 25–30 minutes, until the peppers are tender and the cheese is bubbly and golden.
8. Garnish and serve: Top with fresh parsley if you’d like, and enjoy hot.

Expert Tips & Tricks

Best Practices

• Precook the peppers for 5–10 minutes if you like them extra soft.
• Drain excess fat from the meat mixture to avoid soggy peppers.
• Use a baking dish that fits snugly—it helps the peppers hold their shape.

Common Mistakes

• Overfilling the peppers can lead to messy spills during baking.
• Skipping seasoning—don’t! The right balance of spices is what makes the filling sing.

Time-Saving Tips

• Use pre-riced cauliflower and pre-shredded cheese.
• Make the filling a day ahead and just stuff and bake when ready to eat.

Serving Suggestions

Pairings

Keep things keto and fresh with these sides:

• A crisp green salad with olive oil vinaigrette
• Roasted broccoli or asparagus
• Cauliflower mash

Or add a bit of international flair with a dollop of keto tzatziki or guacamole.

Presentation Ideas

Serve in a rustic baking dish with sprigs of fresh herbs and a drizzle of olive oil. For individual plating, slice a pepper in half and fan it open for a beautiful visual effect.

Beverage Pairings

• For wine: A dry red like Pinot Noir or Cabernet Sauvignon
• For a keto cocktail: Vodka soda with a splash of lime
• Non-alcoholic: Sparkling water with cucumber or mint

Storage & Reheating

Leftover Storage

• Store in an airtight container in the fridge for up to 4 days.
• For longer storage, wrap each pepper in foil and freeze for up to 2 months.

Reheating Methods

• Microwave: Reheat covered for 1–2 minutes until hot.
• Oven: Warm at 350°F for 10–15 minutes.
• Air fryer: 5–7 minutes at 350°F brings back the crispiness.
