Low Carb Casseroles That Are Perfect Right Now

Using fresh zucchini spirals and jarred marinara sauce make this pizza-like casserole a breeze to prepare. Choose a marinara sauce that contains 6 grams of sugar or less per serving or contains “no added sugars.” Spiralized zucchini is available in the produce sections of most groceries, but you can also purchase whole zucchini to spiralize or shave at home. Serves 6.

INGREDIENTS

• 4½   cups zucchini spirals (about 1 lb. zucchini)
• ⅛    tsp. salt
• 1       garlic clove, minced
• ½      lb. lean ground beef (10% fat) or Italian turkey sausage
• 1½   cups tomato-basil marinara sauce
• 1       (14.5 oz.) can no-salt-added petite diced tomatoes, drained
• ¼      tsp. freshly ground pepper
• 2       tsp. olive oil
• 1       small onion, sliced
• 1       green bell pepper, cored and sliced
• 2       cups sliced mushrooms
• 1½   ounces uncured turkey pepperoni, halved
• 1½   cups shredded part-skim mozzarella or Italian cheese blend
• ¼      cup grated Parmesan cheese
• Chopped fresh basil (optional)

INSTRUCTIONS

1. Spread zucchini spirals over a clean kitchen towel. Sprinkle with salt; let sit 30 minutes. Squeeze towel to remove excess moisture from zucchini.
2. Preheat oven to 375 degrees.
3. Heat a large nonstick skillet over medium heat. Add garlic and ground beef; cook 5 minutes or until browned, stirring to crumble. Drain; return to skillet. Add marinara sauce, drained tomatoes, zucchini spirals, and pepper. Simmer 3 minutes or until warm throughout. Spoon mixture into a 13-by-9-inch baking dish coated with cooking spray.
4. Heat oil in skillet over medium-high heat. Add onion and bell pepper; saute 4 minutes or until beginning to turn tender. Add mushrooms, stirring to combine, and cook 2 minutes. Drain any excess liquid from skillet. Using slotted spoon, top zucchini mixture with sauteed vegetables and pepperoni.   Sprinkle with cheeses.
5. Bake at 375 degrees for 15 to 20 minutes or until cheese is melted and beginning to brown on edges. Garnish with fresh basil, if desired.

*Zucchini spirals can be purchased at most groceries in packages ranging from 14 to 15 oz. These typically have 4 to 5 cups of spirals. To make your own spirals, purchase 1 to 1 ¼ lb.  whole zucchini. Trim and then spiralize or use a vegetable peeler to create thin strips.

A lot of recipes for Southwestern-inspired casseroles are heavy in unhealthy carbs like tortilla chips and white rice, as well as high-fat cheese and sour cream. But in this version, whole-grain corn tortillas take the place of chips or white flour tortillas. This swap provides more fiber, fewer calories and carbs, and less saturated fat and sodium. Serves 8.

INGREDIENTS 

• 6  corn tortillas
• Cooking spray
• ⅛   tsp. salt
• 1¼  lbs. lean ground beef (90/10)
• 1  large onion, chopped (about 1½ cups)
• 2½   Tbsp. lower-sodium taco seasoning
• 1  (14.5-oz.) can no-salt-added black beans, drained
• 1   (14.5-oz.) can fire-roasted finely diced tomatoes
• ½   cup fresh refrigerated salsa
• 1   Tbsp. lime juice
• 1½ cups shredded Mexican blend cheese
• ¼  cup chopped green onions
• 4   cups chopped romaine lettuce

INSTRUCTIONS

1. Preheat oven to 400 degrees.
2. Cut tortillas into ½ to 1-inch squares.  Cover a sheet pan with foil; place cut tortillas on lined pan. Coat tortilla pieces with cooking spray; sprinkle with ⅛ tsp. salt, tossing to coat all pieces. Bake at 400 degrees for 12 minutes, stirring tortilla pieces every 3 to 4 minutes. (Tip: Watch pieces on edge to prevent excess browning.) Let cool.
3. Heat nonstick skillet over medium-high heat. Add ground beef and onion. Cook, stirring to crumble beef, 7 minutes or until beef is no longer pink. Drain any excess liquid; return meat mixture to skillet. Add taco seasoning, stirring well. Add beans, tomatoes, salsa and lime juice. Cook 1 to 2 minutes or until warm throughout and slightly thickened.
4. Sprinkle half of toasted tortilla pieces in the bottom of a 13-by-9-inch baking dish coated with cooking spray. Top with half of beef mixture, ¼ cup cheese, and remaining tortilla pieces. Add remaining beef mixture and sprinkle remaining cheese over top.
5. Bake at 400 degrees for 15 to 20 minutes or until warm throughout and cheese is bubbly. Sprinkle with green onions. Let stand 5 minutes. Then cut into 8 pieces or spoon each serving over ½ cup chopped romaine lettuce.

Breakfast casseroles make a hearty meal any time of the day, but many rely on hash browns or bread cubes to bulk up the egg mixture. In Roasted Sweet Potato and Sausage Breakfast Casserole, white potatoes are swapped for more nutrient-dense sweet potatoes. Roasting caramelizes the natural sugars in the sweet potatoes and ensures that they’re tender. Adding a vegetable like spinach means fewer unhealthy carbs and gets in some leafy greens. Serves 8.

INGREDIENTS

• 1       (1-lb.) sweet potato, peeled and cut into ¾-inch cubes (about 3 to 3½ cups)
• 2       tsp. olive oil
• ½      tsp. kosher salt, divided
• ¼      tsp. garlic powder
• 8       oz. mild Italian turkey bulk sausage
• 1       onion, diced
• 4       cups coarsely torn baby spinach
• 9       large eggs
• ¼      cup 1% or low-fat milk
• ½    cup shredded sharp cheddar cheese
• ⅓    cup grated Parmesan cheese

INSTRUCTIONS

1. Preheat oven to 425 degrees. Line a baking sheet with foil; lightly coat foil with cooking spray.
2. Toss sweet potatoes with olive oil, ¼ tsp. salt and garlic powder. Arrange over prepared baking sheet. Bake at 425 degrees for 20 minutes, stirring halfway during cooking. When potatoes are done, reduce oven to 375 degrees.
3. While potatoes bake, place a nonstick skillet over medium heat. Add sausage, stirring to crumble, cooking 5 minutes or until no longer pink. Remove sausage from skillet to drain, reserving drippings in pan. Add onion to pan drippings. Cook 5 minutes, stirring frequently, or until tender. Add spinach, cooking 1 minute or just until wilted.
4. Combine eggs, milk, and remaining ¼ tsp. salt in a large bowl, whisking to combine. Add drained sausage, sweet potatoes, onions and spinach, and half of each cheese, stirring gently to combine. Lightly coat a 13-by-9-inch baking dish with cooking spray. Pour egg mixture into prepared dish. Sprinkle with remaining cheese.
5. Bake at 375 degrees for 20 to 25 minutes or until set in middle.
