Macaroni with plant-based beef & zucchini
One pan does everything. The plant-based beef browns with zucchini in olive oil, then the macaroni, diced tomatoes, milk, water, and bouillon go straight in. Cover, simmer ten minutes, and the pasta absorbs the sauce while the liquid reduces around it.
There is something specific happening with the protein here. Plant-based beef is built on pea protein, which is low in the amino acid methionine. Whole wheat macaroni is high in methionine but low in lysine. Together they compensate for each other’s gaps — 41g of protein from two complementary sources, 14g of fiber, one pan, 25 minutes. The cheddar melts through at the end. The chili powder keeps things from reading as plain.
Ingredients
- onion 0.25
- garlic 1 clove
- zucchini 1
- olive oil 15 ml
- plant-based ground beef 3 oz
- macaroni, whole wheat 3 oz
- diced tomatoes 6 oz
- milk, 2% reduced fat 90 ml
- vegetable bouillon 0.5 cube
- water 210 ml
- chili powder 0.5 tsp
- cheddar cheese, shredded 1 oz
Method
-
Finely chop the onion and mince the garlic. Cut the zucchini into cubes.
-
Heat the oil in a large pan over medium heat. Sauté the onion and garlic for 2 minutes. Add the plant-based beef and zucchini and cook for about 5 minutes.
-
Add the macaroni, diced tomatoes, milk, bouillon cube, water, and chili powder. Stir well and bring to a boil. Once boiling, reduce the heat and cover the pan with a lid. Let everything simmer for 10–12 minutes.
-
Add the cheese and stir until it is melted. Serve immediately.
Cover the pan with a lid during the simmer. The trapped steam cooks the macaroni evenly from all sides, not just the portion submerged in liquid. Without it, the top layer stays chewy while the bottom gets soft.
Plant-based ground beef is built on pea protein, and pea protein has a measurable gap: it is low in methionine, one of the essential amino acids. A DIAAS study measured a pea-based burger at 83 out of 100 for amino acid digestibility — good, but below the 100+ score that beef burgers achieved. Whole wheat macaroni carries wheat protein, which is naturally high in methionine but low in lysine. Pea protein is the opposite — high in lysine, low in methionine. In this recipe, both proteins cook and arrive in your gut together, and their amino acid profiles complement each other. A separate crossover trial with 30 men also confirmed that plant-based meat analogs deliver amino acids less efficiently than red meat overall, so the pairing helps address the biggest gap but does not fully close it.

Behind this recipe
Does plant-based beef have as much protein as real beef?
Gram for gram on the label, they are close. But amino acid digestibility differs. A DIAAS study scored a pea-based burger at 83 out of 100, versus 100+ for beef. The gap comes mainly from methionine, an essential amino acid that pea protein has less of. This recipe pairs the plant-based beef with whole wheat macaroni, whose protein is naturally high in methionine — the two sources partially compensate for each other’s amino acid limitations.
Does the cheese affect the nutrients in the tomatoes?
It can. A randomized crossover trial found that calcium reduced lycopene absorption by up to 83% when taken with a lycopene-rich meal. Cheddar contains calcium, and the diced tomatoes here are a lycopene source. The study used a higher calcium dose (500mg) than what 28g of cheese delivers (~200mg), so the real-world effect is likely smaller. How cheese affects lycopene absorption

Any short pasta that cooks in 10–12 minutes works — penne, fusilli, or rigatoni. Avoid long shapes like spaghetti since they don’t absorb sauce evenly in a one-pot method. Whole wheat holds up better here because it’s sturdier than refined pasta and won’t turn mushy during the extended simmer. And for this recipe specifically, whole wheat provides the methionine that complements the plant-based beef’s protein profile.
Why does the recipe use milk in the sauce?
The milk adds creaminess without heavy cream. As the macaroni simmers, the milk and tomato liquid reduce together into a thick, coating sauce. 90ml of 2% milk is enough to change the texture without overwhelming the tomato flavor.
