Today I'm sharing a recipe for one of my quick meals: roasted sausage with veggies. I'll also share my tips on how to avoid the stove top.

My favorite quick meals avoid the stove top. I pop everything onto a pan and put it into the oven so it can take care of itself in there. I served this over spaghetti squash but you can certainly serve it over regular spaghetti, too.

This is one of my favorite quick meals. Most of the dinner goes on one big pan in the oven at a high temperature. It’s in there for 25-35 minutes, which is a lot of free time on a crazy evening. An added bonus is that the dish is flexible and is happy to stay in the oven for longer. Turn the oven down to 300ºF and leave everything alone for up to an extra 20 minutes.

Another quick and easy oven-baked dinner recipe you might want to check out is my oven-baked Swedish meatballs.

I’d love to hear about your favorite quick meals and your strategies for getting dinner on the table.

One Pan Oven-Roasted Pasta Sauce

Today I’m sharing a recipe for one of my quick meals: roasted sausage with veggies. I’ll also share my tips on how to avoid the stove top.


  • 11lb. bag of frozen pearl onions, defrosted
  • 1 lb. mild Italian chicken sausages
  • 214.5 oz. cans diced tomatoes, drained
  • 8 oz. crimini (baby bella) mushrooms, sliced (save time and buy the ones that come pre-sliced)
  • 2 tbsp. olive oil
  • 1 tsp. kosher salt
  • 1/2 tsp. coarse black pepper
  • 34 sprigs of fresh thyme (or 1/2 tsp dried thyme leaves)


  1. Preheat the oven to 450ºF.
  2. Put the defrosted pearl onions on a microwave-safe plate. Cover with plastic wrap and microwave on high for 4 minutes. This is to get the cooking process started and to soften them a bit.
  3. Cut the sausages into 1/2″ pieces.
  4. On a very large pan (mine is 18″x13″, use the biggest one that will fit in your oven) use a spatula to combine the drained tomatoes, mushrooms, olive oil, salt, pepper, thyme sprigs and the warmed onions (but not any accumulated liquid). Spread everything out on the pan making sure that the sausage pieces are all separated and that they haven’t clumped up in groups.
  5. Put the pan into the oven even if it hasn’t finished pre-heating. Cook until the juices are bubbling, you can hear some sizzling and the sausage pieces are cooked through and no longer pink in the center, about 25 minutes (roasting for another 10 minutes deepens the flavor. If you want to leave it for longer, at that point, reduce the temperature to 300ºF and let it be for another 20 minutes more).
  6. Remove the sausage pan from the oven. Stir everything up once, remove the thyme sprigs and then transfer the roasted mixture to a serving bowl.
  7. To serve, pile strands of spaghetti squash or spaghetti onto plates and top with the roasted tomatoes and sausages. Use slices of wholesome bread to soak up all the lovely juices, if desired.


This recipe calls for a defrosted bag of frozen pearl onions. These are a wonderful convenience item found in your grocery store with the frozen vegetables. Why do I love them? I don’t have to do any peeling or chopping, the kids can easily pick them out of their meal if they don’t like onions and they taste amazing. The only thing is that you have to defrost them before use. The night before, pop the bag of onions on a large plate and put it in the fridge overnight. If you forget, no worries! Empty the bag of onions into a microwave-safe dish, cover and microwave on high for 4 minutes, stir and then another 4 minutes. If all else fails, just use a regular large onion, chopped (but don’t put it in the microwave as detailed in step #2).

    I’m with you on this one – sometimes you can’t beat a meal you can just toss together and walk away from. It seems lately there is never enough time!

      Being able to walk away really is key. And with the high temp, you develop great flavor too. Win-win! Nice seeing you online again!

      Thanks Katie! I really do love avoiding the stove. But erm…Carb free? I think we eat an entire loaf of bread when we have this for dinner. lol!

    I love it. Avoid the stove is something I try to do on nights I have class! Thanks for this great recipe.

      It is a great strategy for a student with evening classes, you’re right! You can get home, throw everything into the oven and then go check your email, turn on the tv, change into some cozy clothes and then sit down to eat. I miss those days!!!
