This healthy sheet pan dinner made of turkey meatballs and veggies couldn’t be easier to whip up for weeknight meals. The meatballs incorporate oat flour instead of breadcrumbs (you’d never know!) for added fiber. And most of the veggies are pre-cut or frozen for ultimate convenience factor.

If the thought of weeknight dinners makes you immediately let out a sigh of exhaustion, we’re here to help. And we get it! It is not easy to balance a busy schedule and feel inspired to make a nutritious meal every night. This healthy sheet pan dinner recipe takes two pans and 10 minutes of prep to execute, plus minimal chopping is required.

Not only is it easy, it’s super healthy. Meatballs are traditionally made with breadcrumbs. For this recipe, we used oat flour in lieu of breadcrumbs. Why oat flour? We use oats in so many of our recipes because they provide a laundry list of health benefits when eaten on the reg. For example, oats are an incredible source of soluble fiber and resistant starch. Both aid in supporting a healthy gut microbiome (1), which is essential to our overall health. Soluble fiber helps to increase feelings of fullness (2), which supports weight loss efforts, has been shown to lower cholesterol levels (3), and lowers blood sugar levels after eating (4).

High fiber sheet pan dinner nutrition facts


At every meal, it’s important to include a significant source of protein to keep you full and help maintain lean body mass. In this recipe, we used turkey as the main protein. Not only is turkey high in protein, it also boasts an impressive nutrient profile. It provides a significant amount of niacin, vitamin b12, and selenium (5) – all of which are essential vitamins and minerals.

Selenium, in particular, is a mineral that doesn’t receive much attention but plays a vital role in our metabolic health. The thyroid needs selenium in order to produce thyroid hormones. Thyroid function and hormones greatly impact our metabolic rate. Eating enough selenium containing foods, like turkey, can help prevent thyroid issues related to selenium deficiency (6).

Cauliflower rice

We know, we know: cauliflower has been having a moment. But there’s a reason for that! Cauliflower is one of the most versatile veggies out there; not to mention, it’s packed with health-promoting nutrients and non-nutrients (like antioxidants).

In case you were wondering, cauliflower rice has no actual rice in it. It’s simply cauliflower that manufacturers cut into a rice-like shape in order to mimic the mouthfeel of actual rice.

Cauliflower rice can be a great swap for regular rice. Especially for people wanting to lose weight. There are several reasons for this. First, cauliflower rice is higher in fiber and lower in calories than both cooked white and brown rice  (7, 8, 9). Boosting fiber intake leads to greater fullness, and because we can’t fully break fiber down in the body (it’s indigestible), we extract a negligible amount of calories from it. This is why high fiber foods tend to be weight loss friendly.

Also, cauliflower rice is less calorie dense than white and brown rice. In fact, 100g of cauliflower rice contains 24 calories whereas 100g of cooked brown rice contains 122 calories (7, 8). Put simply, you could eat about 5 times as much cauliflower rice than cooked brown rice for the same amount of calories. This is helpful for weight loss because when we eat a large volume of food, it physically stretches our stomach, sending a signal to our brain that we are full (you can read more about this in our post on overeating). Research has shown that eating foods with low calorie densities can help with weight loss (10).

Sweet potato and carrots

Seeing lots of orange in the photos of this recipe? That’s the beta-carotene in the sweet potato wedges and carrot slices. Beta-carotene is actually a pigment found in plants which gives them color. When we consume it in foods, the body converts it to vitamin A. Vitamin A then acts as an antioxidant, helping to combat inflammation (11). Pretty cool, right?
