Bulgur & Lentil Stuffed Zucchini
Zucchini boats loaded with a spiced bulgur and lentil filling, finished with a layer of melted cheddar. The filling starts with garlic and onion sautéed in olive oil with oregano, thyme, paprika, and cumin, then builds from there, then tomato paste, diced tomatoes, and lentils simmered together before the cooked bulgur folds in.
20 minutes from cutting board to table. 28g of protein from the bulgur-lentil pairing, 15g of fiber, and 744 kcal in a single serving that covers dinner without needing a side.

Ingredients
- zucchini 1
- olive oil 1.5 tablespoon
- bulgur 3 ounces
- red onion 0.25
- garlic 1 clove
- lentils, canned 2 ounces
- oregano, dried 0.5 teaspoon
- thyme, dried 0.5 teaspoon
- paprika (ground spice) 0.5 teaspoon
- ground cumin 0.5 teaspoon
- tomato paste 1 tablespoon
- diced tomatoes 4 ounces
- water 2 fluid ounces
- vegetable bouillon 0.5 cube
- cheddar cheese, shredded 1 ounce
Method
-
Preheat the oven to 375°F (190°C).
-
Halve the zucchini lengthwise and scoop out the flesh with a spoon to create boat shapes. Place the halves in a baking dish and lightly brush them with half of the oil. Roast the zucchini boats in the oven for 10 minutes.
-
Cook the bulgur according to the package instructions.
-
Finely chop the red onion and garlic. Rinse the lentils and let them drain in a colander.
-
Heat the remaining oil in a pan over medium heat and sauté the onion and garlic for about 2 minutes. Add the oregano, thyme, paprika and cumin, along with the tomato paste and cook for 1 more minute.
-
Add the diced tomatoes, water, bouillon cube and lentils to the pan. Let the mixture simmer for 5 minutes to allow the flavors to blend.
-
Stir the cooked bulgur into the lentil mixture. Season with salt and pepper to taste.
-
Fill the hollowed zucchini with the bulgur and lentil mixture, then sprinkle with cheese.
-
Bake for another 5 minutes. Serve warm.
Give the garlic and onion the full two minutes in the pan before adding the tomato paste in step 5. Research found that garlic and onion promote a structural change in lycopene (the pigment that makes tomatoes red), converting it to a form the body absorbs 8.5 times more efficiently. That brief sauté with the oil is where the conversion starts.
Why This Works
Behind this recipe
Does the cheese affect the lycopene in the tomatoes?
It can. Research found that calcium reduced lycopene absorption by up to 83% in controlled settings. This recipe uses 28g of cheddar, so there is some competition. But the garlic and olive oil are working in the opposite direction. Garlic converts lycopene to a form absorbed 8.5 times more efficiently, and olive oil acts as the carrier. In a real meal with all of these ingredients together, the interaction is more complex than any single lab number suggests.
Where does the 15 grams of fiber come from?
Mostly from the bulgur and lentils. Both sit near the top of the fiber-per-serving chart among pantry staples. The zucchini and tomatoes add a few grams, but the grain-legume base does the heavy lifting. Pooled research across 62 trials found fiber intake independently supported fat loss outcomes.
Read the full evidence reviewCan I swap bulgur for a different grain?
Quinoa and couscous both work. Quinoa adds a few extra grams of protein per serving. Couscous cooks faster but has less fiber. Bulgur is one of the highest-fiber grains available, so the 15g fiber total will drop with most substitutes. The spice blend and filling method stay the same regardless.
Is this enough protein for a full dinner?
28g of protein from two complementary plant sources (lentils and bulgur) plus the cheddar. For a single-person dinner, that covers a solid portion. If you need more, a side of Greek yogurt bumps the total without changing the recipe.
